Contributions to open source projects

false

Mozilla

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.

false

OpenSSL

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.

Unmaintained miscellaneous software

iCalCopy

iCalCopy copies events and to do items from one iCal calendar to another.
