Method Summary

static String	computePasswordHash(String password, byte[] salt) Uses PBKDF2WithHmacSHA1 to hash the password using the given salt, returning the has in encoded hexadecimal form.
static String	computePasswordHash(String password, String salt) Converts the salt into a byte array using stringToSalt(String) and then calls computePasswordHash(String, byte[])
static byte[]	generateRandomSalt() Generates a random byte array to be used as a salt for computePasswordHash(String, byte[])
static byte[]	stringToSalt(String string) Uses SHA-1 to hash the given string and returns the byte array.

Method Detail

computePasswordHash

public static String computePasswordHash(String password,
                                         String salt)

Converts the salt into a byte array using stringToSalt(String) and then calls computePasswordHash(String, byte[])

computePasswordHash

public static String computePasswordHash(String password,
                                         byte[] salt)

Uses PBKDF2WithHmacSHA1 to hash the password using the given salt, returning the has in encoded hexadecimal form. If the password is empty, returns the salt.

generateRandomSalt

public static byte[] generateRandomSalt()

Generates a random byte array to be used as a salt for computePasswordHash(String, byte[])

stringToSalt

public static byte[] stringToSalt(String string)

Uses SHA-1 to hash the given string and returns the byte array.
