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] [-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
-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.
