nevermind guys thanks
I found a fix for this

I had to use the Base64 decoder before decrypting the message

Hello guys.

I have been trying to encrypt with the Cipher class for a while now and I'm still getting issues. I'm having problems with the padding and with the byte array size. I receive this exception "Input length must be multiple of 8 when decrypting with padded cipher" This is the code I wrote:

public CipherClass() { try { cipher = Cipher.getInstance(CIPHER_ALGO); secKey = SecretKeyFactory.getInstance(CIPHER_ALGO).generateSecret(new DESedeKeySpec(new BigInteger(KEY, 16).toByteArray())); } catch(GeneralSecurityException e) { e.printStackTrace(); } } private String encrypt(String text) { try { cipher.init(Cipher.ENCRYPT_MODE, secKey); Base64 encoder = new Base64(); return new String(encoder.encode(cipher.doFinal(text.getBytes()))); } catch(GeneralSecurityException e) { e.printStackTrace(); } return ""; } private String decrypt(String text) { try { cipher.init(Cipher.DECRYPT_MODE, secKey); Base64 decoder = new Base64(); return new String(decoder.decode(cipher.doFinal(text.getBytes()))); } catch (Exception e) { e.printStackTrace(); } return ""; }

I also tried using Hex instead of Base64 and I'm receiving this exception: "Given final block not properly padded"

please help me out, to find error. thanks in advance.
