-                                (~2KB smaller and ~25% slower) (default OFF)
- * WOLFSSL_SHA256_BY_SPEC:     Uses the Ch/Maj based on SHA256 specification

- * WOLFSSL_SHA256_ALT_CH_MAJ:  Alternate Ch/Maj that is easier for compilers to
-                                optimize and recognize as SHA256 (default OFF)
- * SHA256_MANY_REGISTERS:      A SHA256 version that keeps all data in registers
-                                and partial unrolled (default OFF)
