PASSWD(1)

NAME
openssl-passwd, 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.
