Method Summary

static byte[]	decrypt(byte[] value, SecretKeySpec skeySpec) Decrypts the value using the passed in key.
static byte[]	encrypt(byte[] value, SecretKeySpec skeySpec) Encrypts the value using the passed in key.
static SecretKeySpec	generateRandomKey() Generates a random secret key.
static SecretKeySpec	getSecretKey() Calls getSecretKey(String fileName) with the default filename.
static SecretKeySpec	getSecretKey(String fileName) Reads in a stored secret key from a properties file and creates a SecretKeySpec object from it.
static SecretKeySpec	getSecretKeySpec(String key)
