so you can continue with the rest, I'm too lazy for that ;)

If you compare the Base64 decodes characters with the plaintext a pattern
seems to emerge.
a 61
i 69 -
----------
8
b 62
r 72 -
----------
10
c 63
{ 7B -
----------
18
I know the signs are wrong BTW. Each charcter appears to be transformed
before being base 64 encoded.
'a' = 'a' + 0x08;
'b' = 'b' + 0x10;
'c' = 'c' + 0x18;
Without any other crypts to go on I can't test this pattern further.
Perhaps the pattern starts again at character 4, which might explain some
of the behaviour noticed by others. There was mention of a decoder for
these crypts; can someone post a URL with the details? What are these
crypts used for anyway?
