zmap/zmap
Aug 2013 - Dec 2013
ZMap is a fast single packet network scanner designed for Internet-wide network surveys.
Role in this project:
Back-end Developer
Back-end DeveloperContributions:55 commits in 3 months
Contributions summary:Eric contributed significantly to the `zmap` repository by implementing and refactoring the UDP probe module. They added features to specify different UDP probe configurations, including text, file, and hex-based payloads. Further improvements included adding length checks, integrating logging, and utilizing the close callback for cleanup, enhancing the module's robustness and efficiency. The user also addressed code related issues, which improved the overall quality of the project.

certbot/certbot
Jun 2012 - Jul 2012
Certbot is EFF's tool to obtain certs from Let's Encrypt and (optionally) auto-enable HTTPS on your server. It can also act as a client for any other CA that uses the ACME protocol.
Role in this project:Back-end Developer & Security Engineer
Back-end Developer & Security EngineerContributions:24 commits in 19 days
Contributions summary:Eric primarily focused on enhancing the security and functionality of the "chocolate" components within the Certbot repository. Their work involved refactoring existing code to utilize M2Crypto for cryptographic operations, replacing potentially vulnerable implementations. They also added functionalities such as hashcash to mitigate certain attack vectors. The user also touched upon the implementation of SNI (Server Name Indication) challenge verification.
