need help with markov chain, or possibly another solution for decrypt of AES-256
#12
Hi there,
The script seems to work great, but I am a bit confused about what the cipher text is. Is it just the hex equivalent of the test string in it's encrypted form? Below is the hex of both the encrypted and non-encrypted data. I am only using the word "compressed" for the text string and its encrypted hex equivalent for each hex character for ciphertext. It's been running a while :Smile My cipher text is: F1E2A816C8088054221B. So in the code it looks like this: ciphertext="\x29\xF1\xE2\xA8\x16\xC8\x08\x80\x54\x22\x1b" I have the feeling I am misinterpreting what the cipher text is. Am I on the right track or just heating up my CPU? Smile
Thanks,
Ben

In the encrypted file:
encrypted:
3B7FC3B968A3C5BD1B2D5CA3F4B5AFC78D0600CBFC49DF002478ED6BD1F462141FBCC4CA8E8358ABF1E2A816C8088054221BD958F3807EC978979050BDD71797842B60110BA1D7BA8F14D9A7EC8A20F4C9F1

What I figured out it should look like in it's non-encrypted form:
41206469736B2072656164206572726F72206F63637572726564000D0A424F4F544D475220697320636F6D70726573736564000D0A5072657373204374726C2B416C742B44656C20746F2072657374617274

In plain text: "A disk read error occurred
