badsecrets

A pure python library for identifying the use of known or very weak cryptographic secrets across a variety of platforms. The project is designed to be both a repository of various "known secrets" (for example, ASP.NET machine keys found in examples in tutorials), and to provide a language-agnostic abstraction layer for identifying their use.

Knowing when a 'bad secret' was used is usually a matter of examining some cryptographic product in which the secret was used: for example, a cookie which is signed with a keyed hashing algorithm. Things can get complicated when you dive into the individual implementation oddities each platform provides, which this library aims to alleviate.
