=head1 NAME
|
|
|
|
EVP_MAC_POLY1305 - The Poly1305 EVP_MAC implementation
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
Support for computing Poly1305 MACs through the B<EVP_MAC> API.
|
|
|
|
=head2 Numeric identity
|
|
|
|
B<EVP_MAC_POLY1305> is the numeric identity for this implementation,
|
|
and can be used in functions like EVP_MAC_CTX_new_id() and
|
|
EVP_get_macbynid().
|
|
|
|
=head2 Supported controls
|
|
|
|
The supported controls are:
|
|
|
|
=over 4
|
|
|
|
=item B<EVP_MAC_CTRL_SET_KEY>
|
|
|
|
EVP_MAC_ctrl_str() takes two type strings for this control:
|
|
|
|
=over 4
|
|
|
|
=item "key"
|
|
|
|
The value string is used as is.
|
|
|
|
=item "hexkey"
|
|
|
|
The value string is expected to be a hexadecimal number, which will be
|
|
decoded before passing on as control value.
