Likewise, just as with the Digest scheme, -the key is never included in authenticated requests. Instead, it is used to calculate a request MAC value which is -included in its place. - -However, **Hawk** has several differences from Digest. In particular, while both use a nonce to limit the possibility of -replay attacks, in **Hawk** the client generates the nonce and uses it in combination with a timestamp, leading to less -"chattiness" (interaction with the server). - -Also unlike Digest, this scheme is not intended to protect the key itself (the password in Digest) because -the client and server must both have access to the key material in the clear. - -The primary design goals of this scheme are to: -* simplify and improve HTTP authentication for services that are unwilling or unable to deploy TLS for all resources, -* secure credentials against leakage (e.g., when the client uses some form of dynamic configuration to determine where - to send an authenticated request), and -* avoid the exposure of credentials sent to a malicious server over an unauthenticated secure channel due to client - failure to validate the server's identity as part of its TLS handshake. - -In addition, **Hawk** supports a method for granting third-parties temporary access to individual resources using -a query parameter called _bewit_ (in falconry, a leather strap used to attach a tracking device to the leg of a hawk). - -The **Hawk** scheme requires the establishment of a shared symmetric key between the client and the server, -which is beyond the scope of this module. Typically, the shared credentials are established via an initial -TLS-protected phase or derived from some other shared confidential information available to both the client -and the server. - - -## Replay Protection - -Without replay protection, an attacker can use a compromised (but otherwise valid and authenticated) request more -than once, gaining access to a protected resource. To mitigate this, clients include both a nonce and a timestamp when -making requests. This gives the server enough information to prevent replay attacks. - -The nonce is generated by the client, and is a string unique across all requests with the same timestamp and -key identifier combination. - -The timestamp enables the server to restrict the validity period of the credentials where requests occurring afterwards -are rejected. It also removes the need for the server to retain an unbounded number of nonce values for future checks. -By default, **Hawk** uses a time window of 1 minute to allow for time skew between the client and server (which in -practice translates to a maximum of 2 minutes as the skew can be positive or negative). - -Using a timestamp requires the client's clock to be in sync with the server's clock. **Hawk** requires both the client -clock and the server clock to use NTP to ensure synchronization. However, given the limitations of some client types -(e.g. browsers) to deploy NTP, the server provides the client with its current time (in seconds precision) in response -to a bad timestamp. - -There is no expectation that the client will adjust its system clock to match the server (in fact, this would be a -potential attack vector). Instead, the client only uses the server's time to calculate an offset used only -for communications with that particular server. The protocol rewards clients with synchronized clocks by reducing -the number of round trips required to authenticate the first request. - - -## Usage Example - -Server code: - -```javascript -const Http = require('http'); -const Hawk = require('hawk'); - - -// Credentials lookup function - -const credentialsFunc = function (id, callback) { - - const credentials = { - key: 'werxhqb98rpaxn39848xrunpaw3489ruxnpa98w4rxn', - algorithm: 'sha256', - user: 'Steve' - }; - - return callback(null, credentials); -}; - -// Create HTTP server - -const handler = function (req, res) { - - // Authenticate incoming request - - Hawk.server.authenticate(req, credentialsFunc, {}, (err, credentials, artifacts) => { - - // Prepare response - - const payload = (!err ? `Hello ${credentials.user} ${artifacts.ext}` : 'Shoosh!'); - const headers = { 'Content-Type': 'text/plain' }; - - // Generate Server-Authorization response header - - const header = Hawk.server.header(credentials, artifacts, { payload, contentType: headers['Content-Type'] }); - headers['Server-Authorization'] = header; - - // Send the response back - - res.writeHead(!err ? 200 : 401, headers); - res.end(payload); - }); -}; - -// Start server - -Http.createServer(handler).listen(8000, 'example.com'); -``` - -Client code: - -```javascript -const Request = require('request'); -const Hawk = require('hawk'); - - -// Client credentials - -const credentials = { - id: 'dh37fgj492je', - key: 'werxhqb98rpaxn39848xrunpaw3489ruxnpa98w4rxn', - algorithm: 'sha256' -} - -// Request options - -const requestOptions = { - uri: 'http://example.com:8000/resource/1?b=1&a=2', - method: 'GET', - headers: {} -}; - -// Generate Authorization request header - -const header = Hawk.client.header('http://example.com:8000/resource/1?b=1&a=2', 'GET', { credentials: credentials, ext: 'some-app-data' }); -requestOptions.headers.Authorization = header.field; - -// Send authenticated request - -Request(requestOptions, function (error, response, body) { - - // Authenticate the server's response - - const isValid = Hawk.client.authenticate(response, credentials, header.artifacts, { payload: body }); - - // Output results - - console.log(`${response.statusCode}: ${body}` + (isValid ? ' (valid)' : ' (invalid)')); -}); -``` - -**Hawk** utilized the [**SNTP**](https://github.com/hueniverse/sntp) module for time sync management. By default, the local -machine time is used. To automatically retrieve and synchronize the clock within the application, use the SNTP 'start()' method. - -```javascript -Hawk.sntp.start(); -``` - - -## Protocol Example - -The client attempts to access a protected resource without authentication, sending the following HTTP request to -the resource server: - -``` -GET /resource/1?b=1&a=2 HTTP/1.1 -Host: example.com:8000 -``` - -The resource server returns an authentication challenge. - -``` -HTTP/1.1 401 Unauthorized -WWW-Authenticate: Hawk -``` - -The client has previously obtained a set of **Hawk** credentials for accessing resources on the "`http://example.com/`" -server. The **Hawk** credentials issued to the client include the following attributes: - -* Key identifier: `dh37fgj492je` -* Key: `werxhqb98rpaxn39848xrunpaw3489ruxnpa98w4rxn` -* Algorithm: `hmac sha256` -* Hash: `6R4rV5iE+NPoym+WwjeHzjAGXUtLNIxmo1vpMofpLAE=` - -The client generates the authentication header by calculating a timestamp (e.g. the number of seconds since January 1, -1970 00:00:00 GMT), generating a nonce, and constructing the normalized request string (each value followed by a newline -character): - -``` -hawk.1.header -1353832234 -j4h3g2 -GET -/resource/1?b=1&a=2 -example.com -8000 - -some-app-ext-data - -``` - -The request MAC is calculated using HMAC with the specified hash algorithm "`sha256`" and the key over the normalized request string. -The result is base64-encoded to produce the request MAC: - -``` -6R4rV5iE+NPoym+WwjeHzjAGXUtLNIxmo1vpMofpLAE= -``` - -The client includes the **Hawk** key identifier, timestamp, nonce, application specific data, and request MAC with the request using -the HTTP `Authorization` request header field: - -``` -GET /resource/1?b=1&a=2 HTTP/1.1 -Host: example.com:8000 -Authorization: Hawk id="dh37fgj492je", ts="1353832234", nonce="j4h3g2", ext="some-app-ext-data", mac="6R4rV5iE+NPoym+WwjeHzjAGXUtLNIxmo1vpMofpLAE=" -``` - -The server validates the request by calculating the request MAC again based on the request received and verifies the validity -and scope of the **Hawk** credentials. If valid, the server responds with the requested resource. - - -### Payload Validation - -**Hawk** provides optional payload validation. When generating the authentication header, the client calculates a payload hash -using the specified hash algorithm. The hash is calculated over the concatenated value of (each followed by a newline character): -* `hawk.1.payload` -* the content-type in lowercase, without any parameters (e.g. `application/json`) -* the request payload prior to any content encoding (the exact representation requirements should be specified by the server for payloads other than simple single-part ascii to ensure interoperability) - -For example: - -* Payload: `Thank you for flying Hawk` -* Content Type: `text/plain` -* Algorithm: `sha256` -* Hash: `Yi9LfIIFRtBEPt74PVmbTF/xVAwPn7ub15ePICfgnuY=` - -Results in the following input to the payload hash function (newline terminated values): - -``` -hawk.1.payload -text/plain -Thank you for flying Hawk - -``` - -Which produces the following hash value: - -``` -Yi9LfIIFRtBEPt74PVmbTF/xVAwPn7ub15ePICfgnuY= -``` - -The client constructs the normalized request string (newline terminated values): - -``` -hawk.1.header -1353832234 -j4h3g2 -POST -/resource/1?a=1&b=2 -example.com -8000 -Yi9LfIIFRtBEPt74PVmbTF/xVAwPn7ub15ePICfgnuY= -some-app-ext-data - -``` - -Then calculates the request MAC and includes the **Hawk** key identifier, timestamp, nonce, payload hash, application specific data, -and request MAC, with the request using the HTTP `Authorization` request header field: - -``` -POST /resource/1?a=1&b=2 HTTP/1.1 -Host: example.com:8000 -Authorization: Hawk id="dh37fgj492je", ts="1353832234", nonce="j4h3g2", hash="Yi9LfIIFRtBEPt74PVmbTF/xVAwPn7ub15ePICfgnuY=", ext="some-app-ext-data", mac="aSe1DERmZuRl3pI36/9BdZmnErTw3sNzOOAUlfeKjVw=" -``` - -It is up to the server if and when it validates the payload for any given request, based solely on its security policy -and the nature of the data included. - -If the payload is available at the time of authentication, the server uses the hash value provided by the client to construct -the normalized string and validates the MAC. If the MAC is valid, the server calculates the payload hash and compares the value -with the provided payload hash in the header. In many cases, checking the MAC first is faster than calculating the payload hash. - -However, if the payload is not available at authentication time (e.g. too large to fit in memory, streamed elsewhere, or processed -at a different stage in the application), the server may choose to defer payload validation for later by retaining the hash value -provided by the client after validating the MAC. - -It is important to note that MAC validation does not mean the hash value provided by the client is valid, only that the value -included in the header was not modified. Without calculating the payload hash on the server and comparing it to the value provided -by the client, the payload may be modified by an attacker. - - -## Response Payload Validation - -**Hawk** provides partial response payload validation. The server includes the `Server-Authorization` response header which enables the -client to authenticate the response and ensure it is talking to the right server. **Hawk** defines the HTTP `Server-Authorization` header -as a response header using the exact same syntax as the `Authorization` request header field. - -The header is constructed using the same process as the client's request header. The server uses the same credentials and other -artifacts provided by the client to constructs the normalized request string. The `ext` and `hash` values are replaced with -new values based on the server response. The rest as identical to those used by the client. - -The result MAC digest is included with the optional `hash` and `ext` values: - -``` -Server-Authorization: Hawk mac="XIJRsMl/4oL+nn+vKoeVZPdCHXB4yJkNnBbTbHFZUYE=", hash="f9cDF/TDm7TkYRLnGwRMfeDzT6LixQVLvrIKhh0vgmM=", ext="response-specific" -``` - - -## Browser Support and Considerations - -A browser script is provided for including using a `<script>` tag in [lib/browser.js](/lib/browser.js). It's also a [component](http://component.io/hueniverse/hawk). - -**Hawk** relies on the _Server-Authorization_ and _WWW-Authenticate_ headers in its response to communicate with the client. -Therefore, in case of CORS requests, it is important to consider sending _Access-Control-Expose-Headers_ with the value -_"WWW-Authenticate, Server-Authorization"_ on each response from your server. As explained in the -[specifications](http://www.w3.org/TR/cors/#access-control-expose-headers-response-header), it will indicate that these headers -can safely be accessed by the client (using getResponseHeader() on the XmlHttpRequest object). Otherwise you will be met with a -["simple response header"](http://www.w3.org/TR/cors/#simple-response-header) which excludes these fields and would prevent the -Hawk client from authenticating the requests.You can read more about the why and how in this -[article](http://www.html5rocks.com/en/tutorials/cors/#toc-adding-cors-support-to-the-server) - - -# Single URI Authorization - -There are cases in which limited and short-term access to a protected resource is granted to a third party which does not -have access to the shared credentials. For example, displaying a protected image on a web page accessed by anyone. **Hawk** -provides limited support for such URIs in the form of a _bewit_ - a URI query parameter appended to the request URI which contains -the necessary credentials to authenticate the request. - -Because of the significant security risks involved in issuing such access, bewit usage is purposely limited only to GET requests -and for a finite period of time. Both the client and server can issue bewit credentials, however, the server should not use the same -credentials as the client to maintain clear traceability as to who issued which credentials. - -In order to simplify implementation, bewit credentials do not support single-use policy and can be replayed multiple times within -the granted access timeframe. - - -## Bewit Usage Example - -Server code: - -```javascript -const Http = require('http'); -const Hawk = require('hawk'); - - -// Credentials lookup function - -const credentialsFunc = function (id, callback) { - - const credentials = { - key: 'werxhqb98rpaxn39848xrunpaw3489ruxnpa98w4rxn', - algorithm: 'sha256' - }; - - return callback(null, credentials); -}; - -// Create HTTP server - -const handler = function (req, res) { - - Hawk.uri.authenticate(req, credentialsFunc, {}, (err, credentials, attributes) => { - - res.writeHead(!err ? 200 : 401, { 'Content-Type': 'text/plain' }); - res.end(!err ? 'Access granted' : 'Shoosh!'); - }); -}; - -Http.createServer(handler).listen(8000, 'example.com'); -``` - -Bewit code generation: - -```javascript -const Request = require('request'); -const Hawk = require('hawk'); - - -// Client credentials - -const credentials = { - id: 'dh37fgj492je', - key: 'werxhqb98rpaxn39848xrunpaw3489ruxnpa98w4rxn', - algorithm: 'sha256' -} - -// Generate bewit - -const duration = 60 * 5; // 5 Minutes -const bewit = Hawk.uri.getBewit('http://example.com:8000/resource/1?b=1&a=2', { credentials: credentials, ttlSec: duration, ext: 'some-app-data' }); -const uri = 'http://example.com:8000/resource/1?b=1&a=2' + '&bewit=' + bewit; - -// Output URI - -console.log('URI: ' + uri); -``` - - -# Security Considerations - -The greatest sources of security risks are usually found not in **Hawk** but in the policies and procedures surrounding its use. -Implementers are strongly encouraged to assess how this module addresses their security requirements. This section includes -an incomplete list of security considerations that must be reviewed and understood before deploying **Hawk** on the server. -Many of the protections provided in **Hawk** depends on whether and how they are used. - -### MAC Keys Transmission - -**Hawk** does not provide any mechanism for obtaining or transmitting the set of shared credentials required. Any mechanism used -to obtain **Hawk** credentials must ensure that these transmissions are protected using transport-layer mechanisms such as TLS. - -### Confidentiality of Requests - -While **Hawk** provides a mechanism for verifying the integrity of HTTP requests, it provides no guarantee of request -confidentiality. Unless other precautions are taken, eavesdroppers will have full access to the request content. Servers should -carefully consider the types of data likely to be sent as part of such requests, and employ transport-layer security mechanisms -to protect sensitive resources. - -### Spoofing by Counterfeit Servers - -**Hawk** provides limited verification of the server authenticity. When receiving a response back from the server, the server -may choose to include a response `Server-Authorization` header which the client can use to verify the response. However, it is up to -the server to determine when such measure is included, to up to the client to enforce that policy. - -A hostile party could take advantage of this by intercepting the client's requests and returning misleading or otherwise -incorrect responses. Service providers should consider such attacks when developing services using this protocol, and should -require transport-layer security for any requests where the authenticity of the resource server or of server responses is an issue. - -### Plaintext Storage of Credentials - -The **Hawk** key functions the same way passwords do in traditional authentication systems. In order to compute the request MAC, -the server must have access to the key in plaintext form. This is in contrast, for example, to modern operating systems, which -store only a one-way hash of user credentials. - -If an attacker were to gain access to these keys - or worse, to the server's database of all such keys - he or she would be able -to perform any action on behalf of any resource owner. Accordingly, it is critical that servers protect these keys from unauthorized -access. - -### Entropy of Keys - -Unless a transport-layer security protocol is used, eavesdroppers will have full access to authenticated requests and request -MAC values, and will thus be able to mount offline brute-force attacks to recover the key used. Servers should be careful to -assign keys which are long enough, and random enough, to resist such attacks for at least the length of time that the **Hawk** -credentials are valid. - -For example, if the credentials are valid for two weeks, servers should ensure that it is not possible to mount a brute force -attack that recovers the key in less than two weeks. Of course, servers are urged to err on the side of caution, and use the -longest key reasonable. - -It is equally important that the pseudo-random number generator (PRNG) used to generate these keys be of sufficiently high -quality. Many PRNG implementations generate number sequences that may appear to be random, but which nevertheless exhibit -patterns or other weaknesses which make cryptanalysis or brute force attacks easier. Implementers should be careful to use -cryptographically secure PRNGs to avoid these problems. - -### Coverage Limitations - -The request MAC only covers the HTTP `Host` header and optionally the `Content-Type` header. It does not cover any other headers -which can often affect how the request body is interpreted by the server. If the server behavior is influenced by the presence -or value of such headers, an attacker can manipulate the request headers without being detected. Implementers should use the -`ext` feature to pass application-specific information via the `Authorization` header which is protected by the request MAC. - -The response authentication, when performed, only covers the response payload, content-type, and the request information -provided by the client in its request (method, resource, timestamp, nonce, etc.). It does not cover the HTTP status code or -any other response header field (e.g. `Location`) which can affect the client's behaviour. - -### Future Time Manipulation - -The protocol relies on a clock sync between the client and server. To accomplish this, the server informs the client of its -current time when an invalid timestamp is received. - -If an attacker is able to manipulate this information and cause the client to use an incorrect time, it would be able to cause -the client to generate authenticated requests using time in the future. Such requests will fail when sent by the client, and will -not likely leave a trace on the server (given the common implementation of nonce, if at all enforced). The attacker will then -be able to replay the request at the correct time without detection. - -The client must only use the time information provided by the server if: -* it was delivered over a TLS connection and the server identity has been verified, or -* the `tsm` MAC digest calculated using the same client credentials over the timestamp has been verified. - -### Client Clock Poisoning - -When receiving a request with a bad timestamp, the server provides the client with its current time. The client must never use -the time received from the server to adjust its own clock, and must only use it to calculate an offset for communicating with -that particular server. - -### Bewit Limitations - -Special care must be taken when issuing bewit credentials to third parties. Bewit credentials are valid until expiration and cannot -be revoked or limited without using other means. Whatever resource they grant access to will be completely exposed to anyone with -access to the bewit credentials which act as bearer credentials for that particular resource. While bewit usage is limited to GET -requests only and therefore cannot be used to perform transactions or change server state, it can still be used to expose private -and sensitive information. - -### Host Header Forgery - -Hawk validates the incoming request MAC against the incoming HTTP Host header. However, unless the optional `host` and `port` -options are used with `server.authenticate()`, a malicious client can mint new host names pointing to the server's IP address and -use that to craft an attack by sending a valid request that's meant for another hostname than the one used by the server. Server -implementors must manually verify that the host header received matches their expectation (or use the options mentioned above). - -# Frequently Asked Questions - -### Where is the protocol specification? - -If you are looking for some prose explaining how all this works, **this is it**. **Hawk** is being developed as an open source -project instead of a standard. In other words, the [code](/hueniverse/hawk/tree/master/lib) is the specification. Not sure about -something? Open an issue! - -### Is it done? - -As of version 0.10.0, **Hawk** is feature-complete. However, until this module reaches version 1.0.0 it is considered experimental -and is likely to change. This also means your feedback and contribution are very welcome. Feel free to open issues with questions -and suggestions. - -### Where can I find **Hawk** implementations in other languages? - -**Hawk**'s only reference implementation is provided in JavaScript as a node.js module. However, it has been ported to other languages. -The full list is maintained [here](https://github.com/hueniverse/hawk/issues?labels=port&state=closed). Please add an issue if you are -working on another port. A cross-platform test-suite is in the works. - -### Why isn't the algorithm part of the challenge or dynamically negotiated? - -The algorithm used is closely related to the key issued as different algorithms require different key sizes (and other -requirements). While some keys can be used for multiple algorithm, the protocol is designed to closely bind the key and algorithm -together as part of the issued credentials. - -### Why is Host and Content-Type the only headers covered by the request MAC? - -It is really hard to include other headers. Headers can be changed by proxies and other intermediaries and there is no -well-established way to normalize them. Many platforms change the case of header field names and values. The only -straight-forward solution is to include the headers in some blob (say, base64 encoded JSON) and include that with the request, -an approach taken by JWT and other such formats. However, that design violates the HTTP header boundaries, repeats information, -and introduces other security issues because firewalls will not be aware of these "hidden" headers. In addition, any information -repeated must be compared to the duplicated information in the header and therefore only moves the problem elsewhere. - -### Why not just use HTTP Digest? - -Digest requires pre-negotiation to establish a nonce. This means you can't just make a request - you must first send -a protocol handshake to the server. This pattern has become unacceptable for most web services, especially mobile -where extra round-trip are costly. - -### Why bother with all this nonce and timestamp business? - -**Hawk** is an attempt to find a reasonable, practical compromise between security and usability. OAuth 1.0 got timestamp -and nonces halfway right but failed when it came to scalability and consistent developer experience. **Hawk** addresses -it by requiring the client to sync its clock, but provides it with tools to accomplish it. - -In general, replay protection is a matter of application-specific threat model. It is less of an issue on a TLS-protected -system where the clients are implemented using best practices and are under the control of the server. Instead of dropping -replay protection, **Hawk** offers a required time window and an optional nonce verification. Together, it provides developers -with the ability to decide how to enforce their security policy without impacting the client's implementation. - -### What are `app` and `dlg` in the authorization header and normalized mac string? - -The original motivation for **Hawk** was to replace the OAuth 1.0 use cases. This included both a simple client-server mode which -this module is specifically designed for, and a delegated access mode which is being developed separately in -[Oz](https://github.com/hueniverse/oz). In addition to the **Hawk** use cases, Oz requires another attribute: the application id `app`. -This provides binding between the credentials and the application in a way that prevents an attacker from tricking an application -to use credentials issued to someone else. It also has an optional 'delegated-by' attribute `dlg` which is the application id of the -application the credentials were directly issued to. The goal of these two additions is to allow Oz to utilize **Hawk** directly, -but with the additional security of delegated credentials. - -### What is the purpose of the static strings used in each normalized MAC input? - -When calculating a hash or MAC, a static prefix (tag) is added. The prefix is used to prevent MAC values from being -used or reused for a purpose other than what they were created for (i.e. prevents switching MAC values between a request, -response, and a bewit use cases). It also protects against exploits created after a potential change in how the protocol -creates the normalized string. For example, if a future version would switch the order of nonce and timestamp, it -can create an exploit opportunity for cases where the nonce is similar in format to a timestamp. - -### Does **Hawk** have anything to do with OAuth? - -Short answer: no. - -**Hawk** was originally proposed as the OAuth MAC Token specification. However, the OAuth working group in its consistent -incompetence failed to produce a final, usable solution to address one of the most popular use cases of OAuth 1.0 - using it -to authenticate simple client-server transactions (i.e. two-legged). As you can guess, the OAuth working group is still hard -at work to produce more garbage. - -**Hawk** provides a simple HTTP authentication scheme for making client-server requests. It does not address the OAuth use case -of delegating access to a third party.
