OK. You are right, I was having a serious brain fart (2**8 != 64). I shouldn't try to work when I have a bad cold. Let me try to clarify.

I have a series of these 'binary' strings, which are either 45, 60, 90, or 120 characters in length. And I have several million of these strings. I want to store them in a database, but still using a text based storage and achieving maximum efficiency. I thought I might be able to take substrings of 'binary' digits, and convert them into a series of 64 printable characters (being the max that can be done with ASCII). Since I have aproximately 20 million of these strings, I thought I might want to get maximum efficiency in my text encoding. What would be the recommendation on that?

But, given my brain fart, I might just go with the uuencoded solution.
