=head1 NAME
|
|
|
|
EVP_MAC-Poly1305 - The Poly1305 EVP_MAC implementation
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
Support for computing Poly1305 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 "Poly1305", "default=yes"
|
|
|
|
=back
|
|
|
|
=head2 Supported parameters
|
|
|
|
The general description of these parameters can be found in
|
|
L<EVP_MAC(3)/PARAMETERS>.
|
|
|
|
The following parameter can be set with EVP_MAC_CTX_set_params():
|
|
|
|
=over 4
|
|
|
|
=item "key" (B<OSSL_MAC_PARAM_KEY>) <octet string>
|
|
|
|
=back
|
|
|
|
The following parameters can be retrieved with
|
|
EVP_MAC_CTX_get_params():
|
|
|
|
=over 4
|
|
|
|
=item "size" (B<OSSL_MAC_PARAM_SIZE>) <unsigned integer>
|
|
|
|
=back
|
|
|
|
The "size" parameter can also be retrieved with with EVP_MAC_size().
|
|
The length of the "size" parameter should not exceed that of an B<unsigned int>.
