exception while decrypting a String

[Giovanni Boccacaprina]

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.

nevermind guys thanks
I found a fix for this

I had to use the Base64 decoder before decrypting the message
