* | Create wallet RPCs for PSBTAndrew Chow2018-07-161-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | walletprocesspsbt takes a PSBT format transaction, updates the PSBT with any inputs related to this wallet, signs, and finalizes the transaction. There is also an option to not sign and just update. walletcreatefundedpsbt creates a PSBT from user provided data in the same form as createrawtransaction. It also funds the transaction and takes an options argument in the same form as fundrawtransaction. The resulting PSBT is blank with no input or output data filled in.
* | SignPSBTInput wrapper functionAndrew Chow2018-07-131-0/+26
| | | | | | | | | | | | | | | | The SignPSBTInput function takes a PSBTInput, SignatureData, SigningProvider, and other data necessary for signing. It fills the SignatureData with data from the PSBTInput, retrieves the UTXO from the PSBTInput, signs and finalizes the input if possible, and then extracts the results from the SignatureData and puts them back into the PSBTInput.
* | Methods for interacting with PSBT structsAndrew Chow2018-07-131-0/+132
| | | | | | | | | | | | | | | | | | | | Added methods which move data to/from SignaturData objects to PSBTInput and PSBTOutput objects. Added sanity checks for PSBTs as a whole which are done immediately after deserialization. Added Merge methods to merge a PSBT into another one.
* | Add pubkeys and whether input was witness to SignatureDataAndrew Chow2018-07-131-3/+14
| | | | | | | | | | | | Stores pubkeys in SignatureData and retrieves them when using GetPubKey(). Stores whether the signatures in a SignatureData are for a witness input.

* Remove CombineSignatures and replace testsAndrew Chow2018-07-031-140/+0
| | | | | Removes CombineSignatures and replaces its use in tests with ProduceSignature to test the same behavior for ProduceSignature.
* Replace CombineSignatures with ProduceSignatureAndrew Chow2018-07-031-11/+77
| | | | | | | | | Instead of using CombineSignatures to create the final scriptSig or scriptWitness of an input, use ProduceSignature itself. To allow for ProduceSignature to place signatures, pubkeys, and scripts that it does not know about, we pass down the SignatureData to SignStep which pulls out the information that it needs from the SignatureData.
* Make SignatureData able to store signatures and scriptsAndrew Chow2018-07-031-24/+106
| | | | | | | | | | | | | | | | | In addition to having the scriptSig and scriptWitness, have SignatureData also be able to store just the signatures (pubkeys mapped to sigs) and scripts (script ids mapped to scripts). Also have DataFromTransaction be able to extract signatures and scripts from the scriptSig and scriptWitness of an input to put them in SignatureData. Adds a new SignatureChecker which takes a SignatureData and puts pubkeys and signatures into it when it successfully verifies a signature. Adds a new field in SignatureData which stores whether the SignatureData was complete. This allows us to also update the scriptSig and scriptWitness to the final one when updating a SignatureData with another one.

|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | d40f06a Introduce interface for signing providers (Pieter Wuille) Pull request description: `CKeyStore` is a rich interface that provides many features, including knowledge of scripts and pubkeys for solving, private keys for signing, in addition to watch-only keys and scripts, and distinguishing lack of keys from them just being encrypted. The signing logic in script/sign does not actually need most of these features. Here we introduce a simpler interface (`SigningProvider`) which *only* provides keys and scripts. This is actually sufficient for signing. In addtion, we swap the dependency between keystore and script/sign (keystore now depends on script/script with `CKeyStore` deriving from `SigningProvider`, rather than `CKeyStore` being the interface that signing relies on). This is a very early step towards the design in https://gist.github.com/sipa/125cfa1615946d0c3f3eec2ad7f250a2, separating the concern between deciding what outputs are ours and signing.

Two new configuration options are added: * `-addresstype`, with options `legacy`, `p2sh`, and `bech32`. It controls what kind of addresses are produced by `getnewaddress`, `getaccountaddress`, and `createmultisigaddress`. * `-changetype`, with the same options, and by default equal to `-addresstype`, that controls what kind of change is used. All wallet private and public keys can be used for any type of address. Support for address types dependent on different derivation paths will need a major overhaul of how our internal detection of outputs work. I expect that that will happen for a next major version. The above also applies to imported keys, as having a distinction there but not for normal operations is a disaster for testing, and probably for comprehension of users. This has some ugly effects, like needing to associate the provided label to `importprivkey` with each style address for the corresponding key. To deal with witness outputs requiring a corresponding redeemscript in wallet, three approaches are used: * All SegWit addresses created through `getnewaddress` or multisig RPCs explicitly get their redeemscripts added to the wallet file. This means that downgrading after creating a witness address will work, as long as the wallet file is up to date. * All SegWit keys in the wallet get an _implicit_ redeemscript added, without it being written to the file. This means recovery of an old backup will work, as long as you use new software. * All keypool keys that are seen used in transactions explicitly get their redeemscripts added to the wallet files. This means that downgrading after recovering from a backup that includes a witness address will work. These approaches correspond to solutions 3a, 1a, and 5a respectively from https://gist.github.com/sipa/125cfa1615946d0c3f3eec2ad7f250a2. As argued there, there is no full solution for dealing with the case where you both downgrade and restore a backup, so that's also not implemented. `dumpwallet`, `importwallet`, `importmulti`, `signmessage` and `verifymessage` don't work with SegWit addresses yet. They're remaining TODOs, for this PR or a follow-up. Because of that, several tests unexpectedly run with `-addresstype=legacy` for now.
