Thats an interesting idea. You certainly have more of a grasp on it than I do. Unfortunately, my knowledge of base64 and even base10 encoding is extremely limited. The unmap call in my original post was used from an example in another node.

I looked into Digest::MD5, but found that the smallest result that could be produced from any of the digest functions was 16 bytes from binary digest. The other prduced too many characters.

What I really need is an example of exactly how to do this, if it's possible. My experience with map/unmap is sparse.

Could you post an example? Don't get me wrong, I'm not looking for a handout, but an example with an explanation would help me learn.

Thanks
