Username: 
Password: 
DES Salt:  (optional)
MD5 Salt:  (optional)

Valid salt characters are a-z, A-Z, 0-9, the period '.', and the forward slash '/'. For DES, the salt is 2 random characters from the set of valid characters. The MD5 salt is 12 characters, only 8 of which are random. The MD5 salt always starts with '$1$' and ends with '$'.

The salt is always at the beginning of the password portion of the username:password entry. If you use the same salt, you'll get the same result. This is how passwords are validated since the hashes can't be reversed.
