.SH DESCRIPTION
15
This manual page documents briefly the
16
.B nettle\-hash
17
command.
18
This manual page was written for the Debian GNU/Linux distribution
19
because the original program does not have a manual page.
20
Instead, it has documentation in the GNU Info format; see below.

.\" TeX users may be more comfortable with the \fB<whatever>\fP and
23
.\" \fI<whatever>\fP escape sequences to invode bold face and italics,
24

25
\fBnettle\-hash\fP is a program that computes various message digests.
26
The output is different from the familiar md5sum and sha*sum
27
family. For each file, the file name and a colon is printed first,
28
unless input is read from standard input, in which case nothing is
29
printed. Then the hash is printed in chunks of 64 bits (16 hexadecimal
79 magnus 30
digits) followed by the name of the algorithm. In raw (binary) mode,
76 magnus 31
the hash is not split in chunks and is not followed by a newline.

.SH OPTIONS
34
This program follows the usual GNU command line syntax, with long
35
options starting with two dashes (`-').  A summary of options is
36
included below.  For a complete description, see the Info files.

.TP
41
.B \-l, \-\-length=\fIlength\fP
42
Truncate digests at \fIlength\fP octets. It is an error to specify a
43
\fIlength\fP greater than the normal length of the selected digest.
