openssl-passwd, passwd - compute password hashes
SYNOPSIS
openssl passwd [-help] [-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-help

-crypt

-1 Use the MD5 based BSD password algorithm 1.
-apr1

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