java.lang.Objectcom.mysql.jdbc.Security
class Security
Methods for doing secure authentication with MySQL-4.1 and newer.
Method Summary | |
---|---|
(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! |
(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 |
(package private) static byte[] |
scramble411(java.lang.String password,
java.lang.String seed,
Connection conn)
