Android - decodeBase64 crashes App

Question

I have to encrypt a String but the app doesn\'t reach the encrypt method, it crashes on load.
I\'m using Apache Commons Codec library.

private EditText txt         


        

Answer 1

Simply create an object of Base64 and use it to encode or decode in Android, when using org.apache.commons.codec.binary.Base64 library

To Encode

Base64 ed=new Base64();

String encoded=new String(ed.encode("Hello".getBytes()));

Replace "Hello" with the text to be encoded in String Format.

To Decode

Base64 ed=new Base64();

String decoded=new String(ed.decode(encoded.getBytes()));

Here encoded is the String variable to be decoded

Answer 2

Try this:

// decode data from base 64
    private static byte[] decodeBase64(String dataToDecode)
        {
            byte[] dataDecoded = Base64.decode(dataToDecode, Base64.DEFAULT);
            return dataDecoded;
        }

//enconde data in base 64
        private static byte[] encodeBase64(byte[] dataToEncode)
        {
            byte[] dataEncoded = Base64.encode(dataToEncode, Base64.DEFAULT);
            return dataEncoded;
        }

Answer 3

you are giving a string as an input you should give key.getBytes() to the decode methos
