openssl passwd

compute password hashes 

openssl command


SYNOPSIS

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


DESCRIPTION

The openssl 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. The UNIX standard algorithm crypt() and the MD5-based BSD password algorithm 1 and its Apache variant apr1, and its AIX variant are available.

Options

-help 

Print out a usage message.

-crypt 

uses the crypt() algorithm (default).

-1 

uses the MD5 based BSD password algorithm 1.

-apr1 

uses 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 SHA-crypt.txt.

-salt string 

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

-in file 

reads passwords from file.

-stdin 

reads passwords from stdin.

-noverify 

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

-quiet 

does not output warnings when passwords given at the command line are truncated.

-table 

in the output list, prepends the cleartext password and a TAB character to each password hash.

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

-writerand file 

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


EXAMPLES

openssl passwd -crypt -salt xx password

prints xxj31ZMTZzkVA.

openssl passwd -1 -salt xxxxxxxx password

prints $1$xxxxxxxx$UYCIxa628.9qXjpQCjM4a.

openssl passwd -apr1 -salt xxxxxxxx password

prints $apr1$xxxxxxxx$dxHfLAsjHkDRmG83UXe8K0.
