NAME
     openssl-passwd - compute password hashes

SYNOPSIS
     openssl passwd [-help] [-1] [-apr1] [-aixmd5] [-5] [-6] [-salt string] [-in
     file] [-stdin] [-noverify] [-quiet] [-table] [-reverse] [-rand files]
     [-writerand file] [-provider name] [-provider-path path] [-provparam
     [name:]key=value] [-propquery propq] [password]

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

OPTIONS
     -help
	 Print out a usage message.

     -1  Use the MD5 based BSD password algorithm 1 (default).

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

     -aixmd5
	 Use the AIX MD5 algorithm (AIX variant of the BSD algorithm).

     -5
     -6  Use the SHA256 / SHA512 based algorithms defined by Ulrich Drepper.
	 See <https://www.akkadia.org/drepper/SHA-crypt.txt>.

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

     -in file
	 Read passwords from file.

     -stdin
	 Read passwords from stdin.

     -noverify
	 Don't verify when reading a password from the terminal.

     -quiet
	 Don't output warnings when passwords given at the command line are
	 truncated.

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

     -reverse
	 When the -table option is used, reverse the order of cleartext and
	 hash.

     -rand files, -writerand file
	 See "Random State Options" in openssl(1) for details.

     -provider name
     -provider-path path
     -provparam [name:]key=value
     -propquery propq
	 See "Provider Options" in openssl(1), provider(7), and property(7).

EXAMPLES
       % openssl passwd -1 -salt xxxxxxxx password
       $1$xxxxxxxx$UYCIxa628.9qXjpQCjM4a.

       % openssl passwd -apr1 -salt xxxxxxxx password
       $apr1$xxxxxxxx$dxHfLAsjHkDRmG83UXe8K0

       % openssl passwd -aixmd5 -salt xxxxxxxx password
       xxxxxxxx$8Oaipk/GPKhC64w/YVeFD/

HISTORY
     The -crypt option was removed in OpenSSL 3.0.
