openssl-passwd, passwd - compute password hashes

<h1 id="SYNOPSIS">SYNOPSIS</h1>

openssl passwd [-help] [-crypt] [-1] [-apr1] [-aixmd5] [-5] [-6] [-salt string] [-in file] [-stdin] [-noverify] [-quiet] [-table] [-rand file...] [-writerand file] {password}

<h1 id="DESCRIPTION">DESCRIPTION</h1>

The passwd 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 -in file, from stdin for option -stdin, or from the command line, or from the terminal otherwise.

<h1 id="OPTIONS">OPTIONS</h1>

<dl>

Print out a usage message.

</dd>
<dt id="crypt">-crypt</dt>
<dd>

Use the crypt algorithm (default).

</dd>
<dt id="pod-1">-1</dt>
<dd>

Use the MD5 based BSD password algorithm 1.

</dd>
<dt id="apr1">-apr1</dt>
<dd>

Use the apr1 algorithm (Apache variant of the BSD algorithm).

</dd>
<dt id="aixmd5">-aixmd5</dt>
<dd>

Use the AIX MD5 algorithm (AIX variant of the BSD algorithm).

</dd>
<dt id="pod-5">-5</dt>
<dd>

</dd>
<dt id="pod-6">-6</dt>
<dd>

Use the SHA256 / SHA512 based algorithms defined by Ulrich Drepper. See <a href="https://www.akkadia.org/drepper/SHA-crypt.txt">https://www.akkadia.org/drepper/SHA-crypt.txt</a>.

</dd>
<dt id="salt-string">-salt string</dt>
<dd>

Use the specified salt. When reading a password from the terminal, this implies -noverify.

</dd>
<dt id="in-file">-in file</dt>
<dd>

Read passwords from file.

</dd>
<dt id="stdin">-stdin</dt>
<dd>

Read passwords from stdin.

</dd>
<dt id="noverify">-noverify</dt>
<dd>

Don&#39;t verify when reading a password from the terminal.

</dd>
<dt id="quiet">-quiet</dt>
<dd>

Don&#39;t output warnings when passwords given at the command line are truncated.

</dd>
<dt id="table">-table</dt>
<dd>

In the output list, prepend the cleartext password and a TAB character to each password hash.

</dd>
<dt id="rand-file">-rand file...</dt>
<dd>

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 ; for MS-Windows, , for OpenVMS, and : for all others.

</dd>
<dt id="writerand-file">[-writerand file]</dt>
<dd>

Writes random data to the specified file upon exit. This can be used with a subsequent -rand flag.

</dd>
</dl>
