Field Summary
private static char	PVERSION41_CHAR
private static int	SHA1_HASH_SIZE

 

Constructor Summary
private	Security()           Prevent construction.

 

Method Summary
private static int	charVal(char c)           Returns hex value for given char
(package private) static byte[]	createKeyFromOldPassword(java.lang.String passwd)           Creates key from old password to decode scramble Used in 4.1 authentication with passwords stored pre-4.1 hashing.
(package private) static byte[]	getBinaryPassword(int[] salt, boolean usingNewPasswords)           DOCUMENT ME!
private static int[]	getSaltFromPassword(java.lang.String password)
private static java.lang.String	longToHex(long val)
(package private) static java.lang.String	makeScrambledPassword(java.lang.String password)           Creates password to be stored in user database from raw string.
(package private) static void	passwordCrypt(byte[] from, byte[] to, byte[] password, int length)           Encrypt/Decrypt function used for password encryption in authentication Simple XOR is used here but it is OK as we crypt random strings
(package private) static byte[]	passwordHashStage1(java.lang.String password)           Stage one password hashing, used in MySQL 4.1 password handling
(package private) static byte[]	passwordHashStage2(byte[] hashedPassword, byte[] salt)           Stage two password hashing used in MySQL 4.1 password handling
