SaltedMD5PasswordHasher

public SaltedMD5PasswordHasher()

Construct a new SaltedMD5PasswordHasher with a randomized initial state.

SaltedMD5PasswordHasher

public SaltedMD5PasswordHasher(java.lang.Long pInitialHashState)

Construct a new SaltedMD5PasswordHasher with the given initial state.

Method Detail

getPasswordHashKey

public java.lang.Object getPasswordHashKey()

Returns the hash key (if any) that was used for hashing the password for login. This must be passed to checkPassword() to verify the validity of the hash.

getLoginPasswordHasher

public PasswordHasher getLoginPasswordHasher()

Returns a password hasher instance useful for performing a login. This instance may have a unique password hash key so that each login attempt is hashed differently.

encryptPassword

public java.lang.String encryptPassword(java.lang.String pLogin,
                               java.lang.String pPassword)

Encrypts a password suitably for long-term storage.

checkPassword

public boolean checkPassword(java.lang.String pLogin,
                    java.lang.String pLoginPassword,
                    java.lang.String pEncryptedPassword,
                    java.lang.Object pHashKey)

Returns true if the login password matches the encrypted password.

hashPasswordForLogin

public java.lang.String hashPasswordForLogin(java.lang.String pLogin,
                                    java.lang.String pPassword)

Performs the appropriate hashing function for a login process. This value will later be passed to checkPassword().

generateSalt

public java.lang.String generateSalt()
