Cryptography Coding Standard

Welcome to the Cryptography Coding Standard homepage.

The Cryptography Coding Standard (CCS) is a set of coding rules to prevent the most common weaknesses in software cryptographic implementations. CCS was first presented and discussed at the Internet crypto workshop on Jan 23, 2013 (our slides are available).

The following pages are available:

• Coding rules: the list of coding rules, with for each rule a statement of the problem addressed and one or more proposed solutions

• References: a list of external references

• FAQ: the usual Q&As page

These pages can also be accessed with the navigation bar on the left.

Beyond cryptographic research, secure coding practices also find application in very different industries — from banking to online gaming. For example, platforms offering best slot games rely on encryption and cryptographic standards to protect player data, ensure fairness, and maintain trust. This shows how principles developed in cryptography extend far beyond academic settings into practical, everyday digital experiences.
