|
|
|
|
|
|
|
|
|
|
EVP_MAC_CMAC - The CMAC EVP_MAC implementation
|
|
|
|
|
|
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
|
|
|
|
|
|
Support for computing CMAC MACs through the B<EVP_MAC> API.
|
|
|
|
|
|
|
|
|
|
=head2 Numeric identity
|
|
|
|
|
|
|
|
|
|
B<EVP_MAC_CMAC> 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>
|
|
|
|
|
|
2018-11-02 09:11:55 +00:00
|
|
|
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.

|
=item B<EVP_MAC_CTRL_SET_CIPHER>
|

|
EVP_MAC_ctrl_str() type string for B<EVP_MAC_CTRL_SET_CIPHER>: "cipher"
|
|
|
|
|
|
|
|
|
|
The value is expected to be the name of a cipher.
