=head1 DESCRIPTION
|
|
|
|
The message authentication code functions output the MAC of a supplied input
|
|
file.
|
|
|
|
=head1 OPTIONS
|
|
|
|
=over 4
|
|
|
|
=item B<-help>
|
|
|
|
Print a usage message.
|
|
|
|
=item B<-in> I<filename>
|
|
|
|
Input filename to calculate a MAC for, or standard input by default.
|
|
Standard input is used if the filename is '-'.
|
|
Files and standard input are expected to be in binary format.
|
|
|
|
=item B<-out> I<filename>
|
|
|
|
Filename to output to, or standard output by default.
|
|
|
|
=item B<-binary>
|
|
|
|
Output the MAC in binary form. Uses hexadecimal text format if not specified.
|
|
|
|
=item B<-cipher> I<name>
|
|
|
|
Used by CMAC and GMAC to specify the cipher algorithm.
|
|
For CMAC it should be a CBC mode cipher e.g. AES-128-CBC.
|
|
For GMAC it should be a GCM mode cipher e.g. AES-128-GCM.
|
|
|
|
=item B<-digest> I<name>
|
|
|
|
Used by HMAC as an alphanumeric string (use if the key contains printable
|
|
characters only).
|
|
The string length must conform to any restrictions of the MAC algorithm.
|
|
To see the list of supported digests, use C<openssl list -digest-commands>.
|
|
|
|
=item B<-macopt> I<nm>:I<v>
|
|
|
|
Passes options to the MAC algorithm.
|
|
A comprehensive list of controls can be found in the EVP_MAC implementation
|
|
documentation.
|
|
Common parameter names used by EVP_MAC_CTX_get_params() are:

|
|
|
=over 4
|
|
|
|
=item B<key:>I<string>
|
|
|
|
Specifies the MAC key as an alphanumeric string (use if the key contains
|
|
printable characters only).
|
|
The string length must conform to any restrictions of the MAC algorithm.
|
|
A key must be specified for every MAC algorithm.
|
|
|
|
=item B<hexkey:>I<string>
|
|
|
|
Specifies the MAC key in hexadecimal form (two hex digits per byte).
|
|
The key length must conform to any restrictions of the MAC algorithm.
|
|
A key must be specified for every MAC algorithm.
|
|
|
|
=item B<iv:>I<string>
|
|
|
|
Used by GMAC to specify an IV as an alphanumeric string (use if the IV contains
|
|
printable characters only).
|
|
|
|
=item B<hexiv:>I<string>
|
|
|
|
Used by GMAC to specify an IV in hexadecimal form (two hex digits per byte).
|
|
|
|
=item B<size:>I<int>
|
|
|
|
Used by KMAC128 or KMAC256 to specify an output length.
|
|
The default sizes are 32 or 64 bytes respectively.
|
|
|
|
=item B<custom:>I<string>
|
|
|
|
Used by KMAC128 or KMAC256 to specify a customization string.
|
|
The default is the empty string "".
|
|
|
|
=item B<digest:>I<string>
|
|
|
|
This option is identical to the B<-digest> option.
|
|
|
|
=item B<cipher:>I<string>
|
|
|
|
This option is identical to the B<-cipher> option.

|
|
|
|
=item I<mac_name>
|
|
|
|
Specifies the name of a supported MAC algorithm which will be used.
|
|
To see the list of supported MAC's use the command C<openssl list
|
|
-mac-algorithms>.

=head1 EXAMPLES
|
|
|
|
To create a hex-encoded HMAC-SHA1 MAC of a file and write to stdout:
|
|
|
|
openssl mac -digest SHA1 \
|
|
-macopt hexkey:000102030405060708090A0B0C0D0E0F10111213 \
|
|
-in msg.bin HMAC
|
|
|
|
To create a SipHash MAC from a file with a binary file output:
|
|
|
|
openssl mac -macopt hexkey:000102030405060708090A0B0C0D0E0F \
|
|
-in msg.bin -out out.bin -binary SipHash
|
|
|
|
To create a hex-encoded CMAC-AES-128-CBC MAC from a file:
|
|
|
|
openssl mac -cipher AES-128-CBC \
|
|
-macopt hexkey:77A77FAF290C1FA30C683DF16BA7A77B \
|
|
-in msg.bin CMAC
|
|
|
|
To create a hex-encoded KMAC128 MAC from a file with a Customisation String
|
|
'Tag' and output length of 16:
|
|
|
|
openssl mac -macopt custom:Tag -macopt hexkey:40414243444546 \
|
|
-macopt size:16 -in msg.bin KMAC128
|
|
|
|
To create a hex-encoded GMAC-AES-128-GCM with a IV from a file:
|
|
|
|
openssl mac -cipher AES-128-GCM -macopt hexiv:E0E00F19FED7BA0136A797F3 \
|
|
-macopt hexkey:77A77FAF290C1FA30C683DF16BA7A77B -in msg.bin GMAC
|
|
|
|
=head1 NOTES
|
|
|
|
The MAC mechanisms that are available will depend on the options
|
|
used when building OpenSSL.
|
|
Use C<openssl list -mac-algorithms> to list them.
