Hi , I've tried to implement the same steps as discussed in AES .NET
but with no success , i can't seem to get java and slowAes to play toghter ... attached is my code i'm sorry i can't add more this is my first time trying to deal with encryption would appreciate any help
private static final String ALGORITHM = "AES";
private static final byte[] keyValue = getKeyBytes("12345678901234567890123456789012");
private static final byte[] INIT_VECTOR = new byte[16];
private static IvParameterSpec ivSpec = new IvParameterSpec(INIT_VECTOR);
public static void main(String[] args) throws Exception {
String encoded = encrypt("watson?");
System.out.println(encoded);
}
private static Key generateKey() throws Exception {
Key key = new SecretKeySpec(keyValue, ALGORITHM);
// SecretKeyFactory keyFactory = SecretKeyFactory.getInstance(ALGORITHM);
// key = keyFactory.generateSecret(new DESKeySpec(keyValue));
return key;
}
private static byte[] getKeyBytes(String key) {
byte[] hash = DigestUtils.sha(key); // key.getBytes()
byte[] saltedHash = new byte[16];
System.arraycopy(hash, 0, saltedHash, 0, 16);
return saltedHash;
}
public static String encrypt(String valueToEnc) throws Exception {
Key key = generateKey();
Cipher c = Cipher.getInstance("AES/CBC/PKCS5Padding");
c.init(Cipher.ENCRYPT_MODE, key,ivSpec);
byte[] encValue = c.doFinal(valueToEnc.getBytes());
String encryptedValue = new BASE64Encoder().encode(encValue);
return encryptedValue;
}
public static String decrypt(String encryptedValue) throws Exception {
Key key = generateKey();
Cipher c = Cipher.getInstance(ALGORITHM);
c.init(Cipher.DECRYPT_MODE, key);
byte[] decordedValue = new BASE64Decoder().decodeBuffer(encryptedValue);
byte[] decValue = c.doFinal(decordedValue);
String decryptedValue = new String(decValue);
return decryptedValue;
}
the bytes returned are different thanks in advance .
