About SM3

SM3 is a cryptographic hash algorithm released by the State Cryptography Administration of China, with a digest length of 256 bits (32 bytes), comparable in security to SHA-256. Widely used in digital signatures, message authentication codes, key generation and other scenarios.

Steps

1. Enter the text to hash; 2. Click 'Compute Hash' to get the SM3 digest (HEX format).

Notes

SM3 output is always 256 bits (64 HEX characters); same input always produces the same output (deterministic hash); any small change in input produces a completely different hash value (avalanche effect).
