SM2 vs RSA: How to Choose Between Chinese and International Public-Key Crypto

SM2 versus RSA compared: security strength (256-bit SM2 ≈ 3072-bit RSA), performance (signing vs verification tradeoffs), key sizes, the C1C3C2/C1C2C3 ciphertext format pitfall, Chinese compliance requirements, and how to verify with an online SM2 tool.

Chinese National Cryptography (SM2/SM3/SM4/SM9/ZUC): A Developer's Introduction

Introduction to China's commercial cryptography: what SM2, SM3, SM4, SM9 and ZUC each do, how they map to RSA/SHA/AES, a selection decision tree, TLCP vs RFC 8998 boundaries, compliance drivers, and what browser tools can and cannot verify.
