 makekey 

Description

Produces crypt password hashes. This command could be used to automatically populate a password database from known passwords, or to make hashes of prospective passwords that could 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 thirteen-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.
