kerrylinux / ccs_engine_102

A demo OpenSSL 1.0.2 engine provides SM2/SM3/SM4 algorithms.

CCS Engine

Getting Started

CCS_Engine is a demonstration project to show people 'How to create your own OpenSSL engine'.

CCS_Engine implements:

• SM2 (ec based cryptosystem)
• SM3 (message digest)
• SM4 (feistel cipher)

above algorithms are not available in version 1.0.2(see OpenSSL 1.1.1).

Do not use this project directly, as it provides no security guarantee and algorithms implemented in this engine have no optimization at all, thus suffer from horrible performance issues.

If you ever need algorithms not yet provided in any cryptographic libraries, consider implement them via OpenSSL engine, with caution.

Documentation
