What is SM3?

SM3 is a cryptographic hash function defined in the Chinese National Standard GB/T 32905-2016. It generates a fixed-size 256-bit hash value from a message of arbitrary length.

SM3 Properties:

  • Fixed Output Size: SM3 produces a 256-bit hash.
  • Preimage Resistance: It is computationally infeasible to find any input that produces a specific hash value.
  • Second Preimage Resistance: Given an input, it is computationally infeasible to find a different input that produces the same hash value.
  • Collision Resistance: It is computationally infeasible to find two different inputs that produce the same hash value.

SM3 is used in China for security applications, including digital signatures, message authentication, and key derivation. Similar tools include Calculate SHA3-256 and Calculate MD5.
