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.
- --list
- List supported hash algorithms.
- --help
- Show summary of options.
- -V, --version
- Show version of program.
SEE ALSO¶
md5sum(1),
sha1sum(1), etc.
