Bletchley is a real-world cryptanalysis framework. It was created to assist with the detection, analysis, and exploitation of cryptographic flaws and aims to help automate the tedious aspects of this analysis while leaving the security expert in control of the process. It features automated token encoding detection (36 encoding variants), passive ciphertext block length and repetition analysis, a script generator for efficient automation of HTTP requests, and a flexible, multithreaded padding oracle attack library with CBC-R support.
Fivebit is a Python 3 compression library for short text strings. It compresses short strings of text into five bit encoding, which yields a 37.5% reduction for lowercase ASCII. There is also a dictionary for the 1024 most common English words (3 letters or longer). Punctuation, digits, and normal symbols will usually take up 10 bits each, and oddball Unicode characters will take up more space again.
