Why CCM exists but GCM not?

ElenaTyuleneva commented 1 year ago

Hello @zkonge !

Glad to see your interest in IPP Crypto. Let me answer your question. 

Why CCM exists but GCM not?

Currently, we support the next modes for SM4 algorithm: ECB, CBC, CFB, OFB, CTR, CCM. GCM is not currently supported. 

Is SM4-GCM mode important for you? Could you please share the application/use-case where you use this algorithm?

Regarding the request to implement this mode:  Please, submit your feature request via Intel online center - https://supporttickets.intel.com/s/?language=en_US - with a description of why this mode is important for you.
