Subject Re: Binary to Base64 Conversion
Date Sun, 14 May 2017 10:59:17 GMT
I don't think this is not a Groovy problem, so much as a general
programming problem.

The first thing I would point out is that in your example APPUID is not
base64encoded, there is nothing to base64decode.

https://en.wikipedia.org/wiki/Base64


I notice that in your example, APPUID is 16 characters. Is APPUID a UUID
(basically a 16-byte integer)?

If so,

   - You may be looking to create an object of type `java.util.UUID`.
   - You could also possibly use `java.math.BigInteger`
   - Converting the binary array to a String in hex notation may also be
   meaningful.

It all depends on what your final intention is.
