passwd

passwd(1openssl)						      OpenSSL							  passwd(1openssl)

NAME

       passwd - compute password hashes

SYNOPSIS

       openssl passwd [-crypt] [-1] [-apr1] [-salt string] [-in file] [-stdin] [-noverify] [-quiet] [-table] {password}

DESCRIPTION

       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.  The Unix
       standard algorithm crypt and the MD5-based BSD password algorithm 1 and its Apache variant apr1 are available.

OPTIONS

       -crypt
	   Use the crypt algorithm (default).

       -1  Use the MD5 based BSD password algorithm 1.

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

       -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.

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.
