| createKeyFromOldPassword | | static byte[] createKeyFromOldPassword(String passwd) throws NoSuchAlgorithmException(Code) | | Creates key from old password to decode scramble Used in 4.1
authentication with passwords stored pre-4.1 hashing.
Parameters:
passwd - the password to create the key from 20 byte generated key
throws:
NoSuchAlgorithmException - if the message digest 'SHA-1' is not available. |
| getBinaryPassword | | static byte[] getBinaryPassword(int[] salt, boolean usingNewPasswords) throws NoSuchAlgorithmException(Code) | | DOCUMENT ME!
Parameters:
salt - DOCUMENT ME!
Parameters:
usingNewPasswords - DOCUMENT ME! DOCUMENT ME!
throws:
NoSuchAlgorithmException - if the message digest 'SHA-1' is not available. |
| makeScrambledPassword | | static String makeScrambledPassword(String password) throws NoSuchAlgorithmException(Code) | | Creates password to be stored in user database from raw string.
Handles Pre-MySQL 4.1 passwords.
Parameters:
password - plaintext password scrambled password
throws:
NoSuchAlgorithmException - if the message digest 'SHA-1' is not available. |
| passwordCrypt | | static void passwordCrypt(byte[] from, byte[] to, byte[] password, int length)(Code) | | Encrypt/Decrypt function used for password encryption in authentication
Simple XOR is used here but it is OK as we crypt random strings
Parameters:
from - IN Data for encryption
Parameters:
to - OUT Encrypt data to the buffer (may be the same)
Parameters:
password - IN Password used for encryption (same length)
Parameters:
length - IN Length of data to encrypt |
| passwordHashStage1 | | static byte[] passwordHashStage1(String password) throws NoSuchAlgorithmException(Code) | | Stage one password hashing, used in MySQL 4.1 password handling
Parameters:
password - plaintext password stage one hash of password
throws:
NoSuchAlgorithmException - if the message digest 'SHA-1' is not available. |
| passwordHashStage2 | | static byte[] passwordHashStage2(byte[] hashedPassword, byte[] salt) throws NoSuchAlgorithmException(Code) | | Stage two password hashing used in MySQL 4.1 password handling
Parameters:
hash - from passwordHashStage1
Parameters:
salt - salt used for stage two hashing result of stage two password hash
throws:
NoSuchAlgorithmException - if the message digest 'SHA-1' is not available. |
