Name
makekey
Synopsis
makekey
Produces crypt
password hashes. This can be used
to automatically populate a password database from known passwords,
or to make hashes of prospective passwords that can be subjected to
cracking attempts before being put into use.
Options/Usage
makekey
takes no command-line arguments. It
accepts a character string on standard input, consisting of an
eight-character password combined with a two-character
salt
, which is used to permute the DES password
encryption algorithm. (Use man
crypt
for more information.) It prints a
13-character string to standard output, with the first two characters
being the salt, and the other eleven characters being the password
hash. The entire string is suitable for use as the password field in
a standard Unix /etc/passwd
-format file or as
the value of the passwd
property in an Open
Directory entry for a user employing Basic
authentication.
Example
$ echo password12 | /usr/libexec/makekey
