.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
The \fBpasswd\fR command computes the hash of a password typed at
run-time or the hash of each password in a list. The password list is
taken from the named file for option \fB\-in file\fR, from stdin for
option \fB\-stdin\fR, or from the command line, or from the terminal otherwise.
.SH "OPTIONS"
.IX Header "OPTIONS"
.IP "\fB\-help\fR" 4
.IX Item "-help"
Print out a usage message.
.IP "\fB\-crypt\fR" 4
.IX Item "-crypt"
Use the \fBcrypt\fR algorithm (default).
.IP "\fB\-1\fR" 4
.IX Item "-1"
Use the \s-1MD5\s0 based \s-1BSD\s0 password algorithm \fB1\fR.
.IP "\fB\-apr1\fR" 4
.IX Item "-apr1"
Use the \fBapr1\fR algorithm (Apache variant of the \s-1BSD\s0 algorithm).
.IP "\fB\-aixmd5\fR" 4
.IX Item "-aixmd5"
Use the \fB\s-1AIX MD5\s0\fR algorithm (\s-1AIX\s0 variant of the \s-1BSD\s0 algorithm).
.IP "\fB\-5\fR" 4
.IX Item "-5"
.PD 0
.IP "\fB\-6\fR" 4
.IX Item "-6"
.PD
Use the \fB\s-1SHA256\s0\fR / \fB\s-1SHA512\s0\fR based algorithms defined by Ulrich Drepper.
See <https://www.akkadia.org/drepper/SHA\-crypt.txt>.
.IP "\fB\-salt\fR \fIstring\fR" 4
.IX Item "-salt string"
Use the specified salt.
When reading a password from the terminal, this implies \fB\-noverify\fR.
.IP "\fB\-in\fR \fIfile\fR" 4
.IX Item "-in file"
Read passwords from \fIfile\fR.
.IP "\fB\-stdin\fR" 4
.IX Item "-stdin"
Read passwords from \fBstdin\fR.
.IP "\fB\-noverify\fR" 4
.IX Item "-noverify"
Don't verify when reading a password from the terminal.
.IP "\fB\-quiet\fR" 4
.IX Item "-quiet"
Don't output warnings when passwords given at the command line are truncated.
.IP "\fB\-table\fR" 4
.IX Item "-table"
In the output list, prepend the cleartext password and a \s-1TAB\s0 character
to each password hash.
.IP "\fB\-rand file...\fR" 4
.IX Item "-rand file..."
A file or files containing random data used to seed the random number
generator.
Multiple files can be specified separated by an OS-dependent character.
The separator is \fB;\fR for MS-Windows, \fB,\fR for OpenVMS, and \fB:\fR for
all others.
.IP "[\fB\-writerand file\fR]" 4
.IX Item "[-writerand file]"
Writes random data to the specified \fIfile\fR upon exit.
This can be used with a subsequent \fB\-rand\fR flag.
