BCrypt10HashingScheme, SHA1HashingScheme

public interface HashingService

A service API for for unidirectional hashing

Method Summary

Methods

Modifier and Type	Method and Description
boolean	checkPassword(byte[] data, java.lang.String hash) Compares data to a previously created hash
java.lang.String	createHash(byte[] secret, java.lang.Object salt) Create a hash of the given data
java.lang.Object	generateSalt() Generates a salt to be used with the createHash(byte[], Object) method.
java.lang.String	getName() Returns the name of this hashing scheme

Method Detail

getName

java.lang.String getName()

Returns the name of this hashing scheme

createHash

java.lang.String createHash(byte[] secret,
                          java.lang.Object salt)
                            throws HashingException

Create a hash of the given data

Parameters:

secret - The data

salt - A salt to use for hashing

Throws:

java.lang.Exception

HashingException

checkPassword

boolean checkPassword(byte[] data,
                    java.lang.String hash)
                      throws HashingException

Compares data to a previously created hash

Parameters:

data - The data

hash - The hash

Returns:

true if the data equals the data for which the hash was created

Throws:

HashingException

generateSalt

java.lang.Object generateSalt()
                              throws HashingException

Generates a salt to be used with the createHash(byte[], Object) method. This is callable independently, so a functionality may use the same salt for multiple password hashings and then may test hash equality

Throws:

HashingException
