Method Detail

crypt

public static final String crypt(String salt,
                                 String original)
Encrypt a password given the cleartext password and a "salt".

Parameters:
salt - A two-character string representing the salt used to iterate the encryption engine in lots of different ways. If you are generating a new encryption then this value should be randomised.
original - The password to be encrypted.
Returns:
A string consisting of the 2-character salt followed by the encrypted password.

crypt

public static final String crypt(String original)
Encrypt a password given the cleartext password. This method generates a random salt using the 'java.util.Random' class.

Parameters:
original - The password to be encrypted.
Returns:
A string consisting of the 2-character salt followed by the encrypted password.

matches

public static final boolean matches(String encryptedPassword,
                                    String enteredPassword)
Check that enteredPassword encrypts to * encryptedPassword.

Parameters:
encryptedPassword - The encryptedPassword. The first two characters are assumed to be the salt. This string would be the same as one found in a Unix /etc/passwd file.
enteredPassword - The password as entered by the user (or otherwise aquired).
Returns:
true if the password should be considered correct.
