.SH DESCRIPTION
.IX Header "DESCRIPTION"
This 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\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\-1\fR 4
.IX Item "-1"
Use the MD5 based BSD password algorithm \fB1\fR (default).
.IP \fB\-apr1\fR 4
.IX Item "-apr1"
Use the \fBapr1\fR algorithm (Apache variant of the BSD algorithm).
.IP \fB\-aixmd5\fR 4
.IX Item "-aixmd5"
Use the \fBAIX MD5\fR algorithm (AIX variant of the BSD algorithm).
.IP \fB\-5\fR 4
.IX Item "-5"
.PD 0
.IP \fB\-6\fR 4
.IX Item "-6"
.PD
Use the \fBSHA256\fR / \fBSHA512\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 TAB character
to each password hash.
.IP \fB\-reverse\fR 4
.IX Item "-reverse"
When the \fB\-table\fR option is used, reverse the order of cleartext and hash.
.IP "\fB\-rand\fR \fIfiles\fR, \fB\-writerand\fR \fIfile\fR" 4
.IX Item "-rand files, -writerand file"
See "Random State Options" in \fBopenssl\fR\|(1) for details.
.IP "\fB\-provider\fR \fIname\fR" 4
.IX Item "-provider name"
.PD 0
.IP "\fB\-provider\-path\fR \fIpath\fR" 4
.IX Item "-provider-path path"
.IP "\fB\-propquery\fR \fIpropq\fR" 4
.IX Item "-propquery propq"
