passwd(1)
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 termi
nal. - -quiet
- Don't output warnings when passwords given at the com
mand 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 xxj31ZMTZ
zkVA.
openssl passwd -1 -salt xxxxxxxx password prints $1$xxxxxxxx$UYCIxa628.9qXjpQCjM4a..
- openssl passwd -apr1 -salt xxxxxxxx password prints $apr1$xxxxxxxx$dxHfLAsjHkDRmG83UXe8K0.
