EVP_MD-SHA1 - The SHA1 EVP_MD implementation
Support for computing SHA1 digests through the EVP_MD API.
This implementation is available with the FIPS provider as well as the default provider, and is identified with the names "SHA1" and "SHA-1".
This implementation supports the common gettable parameters described in EVP_MD-common(7).
Settable Context Parameters
- "ssl3-ms" (OSSL_DIGEST_PARAM_SSL3_MS) <octet string>
This parameter is set by libssl in order to calculate a signature hash for an SSLv3 CertificateVerify message as per RFC6101. It is only set after all handshake messages have already been digested via OP_digest_update() calls. The parameter provides the master secret value to be added to the digest. The digest implementation should calculate the complete digest as per RFC6101 section 5.6.8. The next call after setting this parameter should be OP_digest_final().
