NAME¶
nettle-hash - compute message digests
SYNOPSIS¶
nettle-hash -a ALGORITHM [OPTIONS] [FILE]...
DESCRIPTION¶
This manual page documents briefly the nettle-hash command. This manual
page was written for the Debian GNU/Linux distribution because the original
program does not have a manual page. Instead, it has documentation in the GNU
Info format; see below.
nettle-hash is a program that computes various message
digests. The output is different from the familiar md5sum and sha*sum
family. For each file, the file name and a colon is printed first, unless
input is read from standard input, in which case nothing is printed. Then
the hash is printed in chunks of 64 bits (16 hexadecimal digits) followed by
the name of the algorithm. In raw (binary) mode, the hash is not split in
chunks and is not followed by a newline.
OPTIONS¶
This program follows the usual GNU command line syntax, with long options
starting with two dashes (`-'). A summary of options is included below. For a
complete description, see the Info files.
- -a, --algorithm=algorithm
- Compute hash using algorithm.
- -l, --length=length
- Truncate digests at length octets. It is an error to specify a
length greater than the normal length of the selected digest.
- --raw
- Produce raw binary output.
- --list
- List supported hash algorithms.
- --help
- Show summary of options.
- -V, --version
- Show version of program.
