Hi all,
I am trying a very simple function to encrypt and decrypt a string.
With the following code the input string is different.
Someone could help me?
The code is not secure but it is not very important at the moment.
String stringKey = "74dc6b9ec2bc29a5490744716e4a7a27";
String message = "FC:A1:3E:2A:79:B2";
SecretKeySpec sks;
Cipher c,d;
try {
sks = new SecretKeySpec(stringKey.getBytes("UTF-8"),"AES");
c = Cipher.getInstance("AES/ECB/ZeroBytePadding");
c.init(Cipher.ENCRYPT_MODE, sks);
c.update(message.getBytes("UTF-8"));
byte[] ciphertext = c.doFinal();
Log.i("CE","crypted text: "+ Base64.encodeToString(ciphertext,
Base64.DEFAULT));
//Decrypt block
d = Cipher.getInstance("AES/ECB/ZeroBytePadding");
d.init(Cipher.DECRYPT_MODE, sks);
d.update(ciphertext);
byte[] deCiphertext =d.doFinal();
Log.i("CE","decrypted text: "+ new String(deCiphertext,"UTF-8"));
} catch ....
Thanks a lot
