Method Detail

crypt

public static final String crypt(String salt,
                                 String original)
                          throws UnsupportedEncodingException

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.

Throws:

UnsupportedEncodingException

crypt

public static final String crypt(String original)
                          throws UnsupportedEncodingException

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.

Throws:

UnsupportedEncodingException

matches

public static final boolean matches(String encryptedPassword,
                                    String enteredPassword)
                             throws UnsupportedEncodingException

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.

Throws:

UnsupportedEncodingException
