NAME
passwd - compute password hashes
SYNOPSIS
openssl passwd [-crypt] [-1] [-apr1] [-salt string] [-in
file] [-stdin] [-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, and from the command
line otherwise. The Unix standard algorithm crypt and the
MD5-based BSD password algorithm 1 and its Apache variant
apr1 are available.
OPTIONS

-1 Use the MD5 based BSD password algorithm 1.
-apr1
Use the apr1 algorithm (Apache variant of the BSD
algorithm).
-salt string

-in file
Read passwords from file.
-stdin

-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
