I have a RSA exponent in the form of a BigInteger. As it seems in an example, I am supposed to get it into some xml. In the example it looks like this: <Exponent>AQAB</Exponent>

SInce there are no == in the end, I assume it is not Base64 encoded. Correct?
So, what form is this and how do I get there?

Yes - if you output it as hex, you won't need Base64

But what about the Q? I thought hex was constructed out of 0123456789ABCDEF.

Yes - what's the problem with that?

Q isn't part of the characters that you express hex with. The reason as it showed in this example is that it was base64.

It could easily be base64 - in fact i don't know what else it could be
