I am working on the assumption that the first few chars could be a randomly generated salt and the rest is equal sized blocks of encrypted content. The random salt results in a different encoding each time.

This is what I have so far and it seems to fit the original encoded message too.

The salt is the first 29 chars.

Each encrypted block is 59 chars.

So for the QBFs : 29 + 6x59

For the original message : 29 + 5x59

Note: I have never come across such sizes for salt and block though. I may be totally off.

Here are some numbers for this approach. Here are another two QBFs
