Nothing much to see here.
The Python package called tomb is the beginnings of a cryptography toolkit.
It currently contains a disorganised mess of xor-ing functions, and a slightly more organised language analysis framework.
Points of interest:
tomb.analysis: Contains an "englishness" function.tomb.cache: Generic caching code, currently caches models.tomb.counting: Functions that produce/update/modify counters.tomb.functions: Miscellaneous mathematical functions.tomb.language: Language modeling code/package.tomb.language.data: A selection of public domain non-fiction text.tomb.language.tables: Builds char/word frequency tables from sample text.
