Open Source Projects

I contribute to open source projects and release tools and libraries. A full list of projects can be found on my GitHub. Here are some of the more interesting ones:


atriage is a triage tool for afl-fuzz that is written in Python. It attempts to de-dupe crash cases and perform exploitability analysis.


python-fastpbkdf2 are Python bindings for the fastpbkdf2 library. It offers a standard library compatible interface with a large improvement in speed.


aead is a Python library that provides authenticated encryption with associated data (AEAD) wrapped up in a simple to use API. It is essentially AES_128_CBC and HMAC_SHA_256 composed with an encrypt-then-mac construction and relies on PyCA's cryptography library for the cryptographic primitives.

See my blog post about the library for more information.


tlsenum is a pure Python TLS enumeration tool that attempts to enumerate what TLS cipher suites a server supports and list them in order of priority. It also performs various tests that checks things like supported versions of TLS and support for TLS-level compression.

PyCA's cryptography

cryptography is the most up-to-date and widely used cryptography library for Python. I contributed a fair amount of patches to it. A full list of my merged commits can be found on GitHub.
