Current and former members of Crypto Services have been involved in several projects:

• BearSSL and Constant-Time Toolkit (CTTK) were built by and are currently maintained by Thomas Pornin.
• CryptoHack (cryptohack.org), a platform with CTF-style cryptographic challenges, was co-founded by Giacomo Pope. It offers challenges covering all sorts of cryptography: hash functions, block ciphers, lattices, zero-knowledge proofs, and more.
• The Matasano Crypto Challenges, aka CryptoPals Challenges were written by former members of the Crypto Services team.
• The CryptoPals Guided Tour was created by Eli Sohl and includes screencasts covering each challenge in detail. The first 19 challenges are available on YouTube either in a playlist on NCC Group’s channel or on Eli’s channel.
• The DASP project and OTF or Open Crypto Audit initiatives such as the OpenSSL audit and TrueCrypt audit.
