SM3 vs SHA-256: Comparing the Chinese and NIST Hash Algorithms

SM3 versus SHA-256: same 256-bit digest strength, structural similarities (Merkle-Damgård), the standard test vectors for integration debugging, hardware acceleration differences, when Chinese compliance mandates SM3, and HMAC's algorithm-agnostic construction.

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.
