Decode Base64 data in Java

Question

I have an image that is Base64 encoded. What is the best way to decode that in Java? Hopefully using only the libraries included with Sun Java 6.

Answer 1

Guava now has Base64 decoding built in.

Use BaseEncoding.base64().decode()

As for dealing with possible whitespace in input use

BaseEncoding.base64().decode(CharMatcher.WHITESPACE.removeFrom(...));
