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 standards: what SM2, SM3, SM4, SM9 and ZUC each do, how they map to RSA/SHA/AES, the TLCP GM-TLS protocol, compliance drivers (等保, government, finance), library landscape (BouncyCastle, sm-crypto, Tongsuo), and online tools for hands-on learning.
