digest - calculate a message digest
/usr/bin/digest -l | [-v] -a algorithm [-t truncation] [file]...
The digest utility calculates the message digest of the given files or stdin using the algorithm specified. If more than one file is given, each line of output is the digest of a single file.
The following options are supported:
Specifies the name of the algorithm to use during the encryption or decryption process. See USAGE, Algorithms, for details.
Displays list of algorithms available on the system. This list can change depending on the configuration of the cryptographic framework.
Verbose output. Includes the algorithm name and filename in the output. This produces output similar to the GNU coreutils digest utilities, md5sum(1), sha1sum(1), sha256sum(1), sha512sum(1), etc.
Specifies the digest truncation length, where t is any positive number less than 512. Valid only for algorithm sha512_t.
The supported algorithms are displayed by the –l option. These algorithms are provided by the Cryptographic Framework. These values are used with the –a option and are case-sensitive.
The following example generates the SHA256 digest of the file /etc/motd:
example$ digest -a sha256 /etc/motd e3b0c44298fc1c149afbf4c8996fb92427ae41e4649b934ca495991b7852b855
The following example displays the SHA512/256 digest of the file /etc/motd:
example $ digest -a sha512_t -t 256 /etc/motd 1917c02fbf36970f354defef8c089adf5767cec93c3ca2b28fe29958c4361e69Example 2 Generating a Directory Manifest
The following example generates a directory manifest with SHA-1:
example$ digest -v -a sha1 /usr/lib/inet/* sha1 (/usr/lib/inet/certdb) = f6d43e6e395d50db24d34e4af4828598c8918b16 sha1 (/usr/lib/inet/certlocal) = 7f74ba4a019b809c7023212b4bda10d9485e071d sha1 (/usr/lib/inet/certrldb) = 1f845d30b8d02066647de04311e74549049852ed sha1 (/usr/lib/inet/dhcp) = e3db5e4ff40a69d13f2497254526c2015d2c37b3 sha1 (/usr/lib/inet/dsvclockd) = b61aad7ed6a0f82145c3c26aedc613ab4a1f032e sha1 (/usr/lib/inet/in.dhcpd) = 382210180c826fbb2e747236c489062bac8cc30b sha1 (/usr/lib/inet/in.iked) = be6061fad725d37256e773dc85f8bd5248649463 sha1 (/usr/lib/inet/in.mpathd) = 5bd6bf0340fd5c4cc0c53f2df158302a0e85f9d0 sha1 (/usr/lib/inet/in.ndpd) = fdb768aebe7e5eb4465e1c1bb5e679b496f5c5c6 sha1 (/usr/lib/inet/in.ripngd) = 4f56a0df2d4a252f581a73c2e84143b920d0b66b sha1 (/usr/lib/inet/wanboot) = a8b8c51c389c774d0be2ae43cb85d1b1439484ae sha1 (/usr/lib/inet/ntpd) = 5b4aff102372cea801e7d08acde9655fec81f07cExample 3 Displaying a List of Available Algorithms
The following example displays a list of available algorithms to digest:
example $ digest -l sha1 md5 sha224 sha256 sha384 sha512 sha512_t sha3_224 sha3_256 sha3_384 sha3_512
The following exit values are returned:
Successful completion.
An error occurred.
