What's the process for going about decrypting these things? I've seen some that are just base64 and the like - but those have obvious patterns. How are you meant to decrypt something when you don't even know the algorithm? Is it just a series of brute forces against different algos?
- jgrahamc 13y agoHave a go at the first one. It's likely to just be a simple cipher: AWVLI QIQVT QOSQO ELGCV IIQWD LCUQE EOENN WWOAO LTDNU QTGAW TSMDO QTLAO QSDCH PQQIQ DQQTQ OOTUD BNIQH BHHTD UTEET FDUEA UMORE SQEQE MLTME TIREC LICAI QATUN QRALT ENEIN RKG You might notice that there are a lot of Q's, perhaps those are E's... You might also look at repeated letters, or common letter pairs.
- ExxKA 13y agoIt doesnt seem like a normal ceasar or ROT algorithm. I am trying it as a "playfair" algorithm at the moment but that seems like a dead end aswell.
- GaryRowe 13y agoProbably not Playfair since there are repeated digraphs.
- gazza126 13y agoI've tried caesar shift using Q as E (based on frequency) so M is A but that failed epicly... also tried a viginere using GCHQ as the key word but again failed epicly :L Not even bothering with Playfair. simple letter to Ascii doesn't work either and i really can't be bothered with going stupidly complicated :/
