About SM3 Hash Generator
SM3 is a cryptographic hash function used in the Chinese National Standard. SM3 is mainly used in digital signatures, message authentication codes, and pseudorandom number generators. The message digest algorithm consists, by default, of 64 rounds and length of 256.
Input: binary bytes (text input uses UTF-8; a file retains its original bytes). Output: text.
Format reference: SM3 background and specification
Example
Use “Try example” to load this public sample and its settings, then run it.
Settings used in this example

Before interpreting the result
Use a checksum to compare exact bytes against a trusted digest. Choose a password hashing function for passwords and a MAC for keyed authentication. MD5 and SHA-1 are unsuitable for new security-sensitive designs.
How to use this page
- Paste your input or open a local file.
- Adjust tool options if needed, then choose Run tool.
- Copy the result or download the original output bytes.
Inputs and results are not added to the public catalogue or saved in the URL. Processing happens in your browser; HTTP Request and DNS over HTTPS send the requests you explicitly run. Files up to 128 MiB can be opened; decompression and image tools may have smaller processing limits. Large results have a shortened preview. Text and HTML downloads use UTF-8; binary downloads preserve output bytes. Pasted text follows browser newline handling; open a file when exact input bytes matter.
