The provider- manuals are meant to describe the general interface for their respective operation. This is not the place to describe implementation specific details. This change creates a number of doc/man7/EVP_MD manuals, one for each algorithm or set of algorithms, as well as doc/man7/EVP_MD-common.pod to describe what's common to them all. While we're at it, correct the SHA3 settable context params array to match what's actually settable.

=head1 NAME
|
|
|
|
EVP_MD-MD5-SHA1 - The MD5-SHA1 EVP_MD implementation
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
Support for computing MD5-SHA1 digests through the B<EVP_MD> API.
|
|
|
|
MD5-SHA1 is a rather special digest that's used with SSLv3.
|
|
|
|
=head2 Identity
|
|
|
|
This implementation is only available with the default provider, and is
|
|
identified with the name "MD5-SHA1".
|
|
|
|
=head2 Gettable Parameters
|
|
|
|
This implementation supports the common gettable parameters described
|
|
in L<EVP_MD-common(7)>.
|
|
|
|
=head2 Settable Context Parameters
|
|
|
|
This implementation supports the following L<OSSL_PARAM(3)> entries,
|
|
settable for an B<EVP_MD_CTX> with L<EVP_MD_CTX_set_params(3)>:
|
|
|
|
=over 4
|
|
|
|
=item "ssl3-ms" (B<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().
