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?
