Code from research projects
Software for prototyping quantum-resistant cryptography. Includes C library of key exchange algorithms and integration into OpenSSL.
Scripts for generating and testing hybrid certificates for post-quantum PKI.
C code implementing various double-authentication-preventing signature schemes.
C code implementing key exchange protocol based on the learning with errors problem.
C code implementing the ring learning with errors primitive as well as a ring-LWE-based key exchange protocol and integration into OpenSSL.
Prototype extension for Mozilla Firefox that performs password-authenticated key exchange with channel bindings.
An Automator action for Mac OS X that allows files to be uploaded and downloaded with scp (the secure copy protocol, part of SSH).
Various snippets of code, including a Solarized colour scheme for tcsh and shell scripts for binary/hex conversion.
Contributions to open source projects
I worked on code for the Mozilla project, or more specifically the Netscape Security Services (NSS) library, which is part of Mozilla. In collaboration with researchers at Sun Microsystems Laboratories, I developed an implementation of elliptic-curve cryptography for the NSS toolkit.
OpenSSL is an open-source cryptography library. While working as an intern at Sun Micrososytems Laboratories, I contributed code for elliptic-curve cryptography (ECC) to OpenSSL. Specifically, our contribution included a library for arithmetic over a characteristic two field, key agreement and signature algorithms, and SSL handshake modifications for ECC.
