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.
