EVP_MD−SHA1 − The SHA1 EVP_MD implementation
Support for computing SHA1 digests through the EVP_MD API.
Identities
This implementation is available with the
FIPS provider as well as the default
provider, and is identified with the names "
SHA1" and "
SHA−1".
Gettable
Parameters
This implementation supports the common gettable parameters
described in EVP_MD−common(7).
Settable
Context Parameters
This implementation supports the following
OSSL_PARAM (3) entries, settable for
an EVP_MD_CTX with
EVP_MD_CTX_set_params(3):
"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().
EVP_MD_CTX_set_params(3), provider−digest(7), OSSL_PROVIDER−FIPS (7), OSSL_PROVIDER−default(7)
