Converting Key to String and back to Key Java

Question

so I\'m trying to convert a Key into a string so I can display it with System.out, and then I want to convert it back to a Key. I am able to convert it to a string with BASE

Answer 1

You never use your BASE64Decoder to un-base-64 your string.

Replace this:

        Key key = new SecretKeySpec(keyString.getBytes(),0,keyString.getBytes().length, "DES");     

with

        byte[] encodedKey = decoder.decodeBuffer(keyString);
        Key key = new SecretKeySpec(encodedKey,0,encodedKey.length, "DES");
