Method Detail

newInstance

public static BCryptPasswordEncryptor newInstance(int costFactor)

Returns a password encryptor that uses the BCrypt algorithm with the specified cost factor.

Parameters:

costFactor - the BCrypt cost factor, must be between and (inclusive).

Returns:

a BCryptPasswordEncryptor instance configured as described above.

Throws:

IllegalArgumentException - if the specified BCrypt cost factor is not between and (inclusive).

encryptPassword

public String encryptPassword(char[] plainPassword)

Description copied from interface: PasswordEncryptor

Encrypts a password.

Specified by:

encryptPassword in interface PasswordEncryptor

Parameters:

plainPassword - the plaintext password as a cleanable char[]

Returns:

the BASE-64 digest of encrypting the specified password

checkPassword

public boolean checkPassword(char[] plainPassword,
                    String storedPassword)

Description copied from interface: PasswordEncryptor

Checks an unencrypted password against an encrypted one to see if they match.

Specified by:

checkPassword in interface PasswordEncryptor

Parameters:

plainPassword - the plaintext password as a cleanable char[]

storedPassword - the (BASE-64) digest from an earlier encryption against which to check the plaintext password

Returns:

true if passwords match, false otherwise

getCostFactor

public int getCostFactor()

Returns the cost factor in use by this instance.

Returns:

the integer cost factor used by this instance.
