Java: Cipher package (encrypt and decrypt). invalid key error
- by noinflection
Hello folks, i am doing a class with static methods to encrypt and decrypt a message using javax.crypto. I have 2 static methods that use ecipher and dcipher in order to do what they are supossed to do i need to initialize some variables (which are static also). But when i try to use it i get InvalidKeyException with the parameters i give to ecipher.init(...). I can't find why. Here is the code:
private static byte[] raw = {-31, 17, 7, -34, 59, -61, -60, -16,
26, 87, -35, 114, 0, -53, 99, -116,
-82, -122, 68, 47, -3, -17, -21, -82,
-50, 126, 119, -106, -119, -5, 109, 98};
private static SecretKeySpec skeySpec;
private static Cipher ecipher;
private static Cipher dcipher;
static {
try {
skeySpec = new SecretKeySpec(raw, "AES");
// Instantiate the cipher
ecipher = Cipher.getInstance("AES");
dcipher = Cipher.getInstance("AES");
ecipher.init(Cipher.ENCRYPT_MODE, skeySpec);
dcipher.init(Cipher.DECRYPT_MODE, skeySpec);
} catch (NoSuchAlgorithmException e) {
throw new UnhandledException("No existe el algoritmo deseado", e);
} catch (NoSuchPaddingException e) {
throw new UnhandledException("No existe el padding deseado", e);
} catch (InvalidKeyException e) {
throw new UnhandledException("Clave invalida", e);
}
}
