SM3 Hash Generator
Generate Chinese standard SM3 hashes for regulatory compliance and financial security.
What Is SM3?
SM3 is the Chinese national cryptographic hash standard that produces a 256-bit hash using a Merkle-Damgård construction with 16 32-bit registers, providing security comparable to SHA-256.

Security Notice
SM3 is suitable for cryptographic integrity checks and fingerprints when used appropriately. Use HMAC or KMAC when you need message authentication, and use a dedicated KDF such as Argon2, bcrypt, or scrypt for password storage.

How to Generate a SM3 hash
- Choose UTF-8, Hex, Base64, or File input mode.
- Enter text, encoded bytes, or choose a local file to process.
- Click Generate SM3 Hash and copy the result.
Example Input
Sample input:
abc
Use this sample input, then copy the generated hash from the result panel.
When Not to Use SM3
- Do not use a plain hash or derivation output directly as password storage without the right password-hashing construction and parameters.
- Do not choose it for non-Chinese compliance contexts unless SM3 is specifically required.
