NAME
mac - calculate message authentication codes of the input
SYNOPSIS
/usr/bin/mac -l | [-v] -a algorithm [-k keyfile] [file...]
DESCRIPTION
The mac utility calculates the message authentication code (MAC) of the given file or files or stdin using the algorithm specified.
If more than one file is given, each line of output is the MAC of a single file.
OPTIONS
The following options are supported:
-a algorithm Specifies the name of the algorithm to use during the encryption or decryption process. See USAGE, Algorithms for details.
Note: Algorithms for producing general length MACs are not supported.
-k keyfile Specifies the file containing the key value for the encryption algorithm. Each algorithm has specific key material require-
ments, as stated in the PKCS#11 specification. If -k is not specified, mac prompts for key material using get-
passphrase(3C).
For information on generating a key file, see dd(1M) or System Administration Guide: Security Services.
-l Displays the list of algorithms available on the system. This list can change depending on the configuration of the crypto-
graphic framework. The keysizes are displayed in bits.
-v Provides verbose information.
USAGE
Algorithms
The supported algorithms are displayed with the -l option. These algorithms are provided by the cryptographic framework. Each supported
algorithm is an alias to the most commonly used and least restricted version of a particular algorithm type. For example, md5_hmac is an
alias to CKM_MD5_HMAC.
These aliases are used with the -a option and are case-sensitive.
Passphrase
When the -k option is not used during encryption and decryption tasks, the user is prompted for a passphrase. The passphrase is manipulated
into a more secure key using the PBKDF2 algorithm specified in PKCS #5.
EXAMPLES
Example 1: Listing available algorithms
example$ mac -l
Algorithm Keysize: Min Max
-----------------------------------
des_mac 64 64
sha1_hmac 8 512
md5_hmac 8 512
Example 2: Getting the message authentication code for a file
example$ mac -v -k mykey -a sha1_hmac /export/foo
sha1_hmac (/export/foo) = 913ced311df10f1708d9848641ca8992f4718057
EXIT STATUS
The following exit values are returned:
0 Successful completion.
>0 An error occurred.
