We now describe parameters instead of controls.
Also, since macros like EVP_MAC_CMAC do not exist any more, we rename
the pod files from EVP_MAC_{algo}.pod to EVP_MAC-{algo}.pod. This
allows getting the documentation like this:
man EVP_MAC CMAC
[skip ci]

=head1 NAME
|
|
|
|
EVP_MAC-HMAC - The HMAC EVP_MAC implementation
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
Support for computing HMAC MACs through the B<EVP_MAC> API.
|
|
|
|
=head2 Identity
|
|
|
|
This implementation is identified with this name and properties, to be
|
|
used with EVP_MAC_fetch():
|
|
|
|
=over 4
|
|
|
|
=item "HMAC", "default=yes"
|
|
|
|
=back
|
|
|
|
=head2 Supported parameters
|
|
|
|
The general description of these parameters can be found in
|
|
L<EVP_MAC(3)/PARAMETER NAMES>.
|
|
|
|
The following parameter can be set with EVP_MAC_CTX_set_params():
|
|
|
|
=over 4
|
|
|
|
=item B<OSSL_MAC_PARAM_KEY> ("key") <octet string>
|
|
|
|
=item B<OSSL_MAC_PARAM_FLAGS> ("flags") <octet string>
|
|
|
|
=item B<OSSL_MAC_PARAM_ENGINE> ("engine") <utf8 string>
|
|
|
|
=item B<OSSL_MAC_PARAM_DIGEST> ("digest") <utf8 string>
|
|
|
|
=item B<OSSL_MAC_PARAM_PROPERTIES> ("properties") <utf8 string>
|
|
|
|
=back
|
|
|
|
The "flags" parameter is passed directly to HMAC_CTX_set_flags().
|
|
|
|
The following parameters can be retrieved with
|
|
EVP_MAC_CTX_get_params():
|
|
|
|
=over 4
|
|
|
|
=item B<OSSL_MAC_PARAM_SIZE> ("size") <unsigned int>
|
|
|
|
=back
|
|
|
|
The "size" parameter can also be retrieved with EVP_MAC_size().
