sm3hash
Pure-Python implementation of SM3, the Chinese national cryptographic hash standard (GB/T 32905-2016). No compiled extensions, no dependencies, works anywhere Python 3.10+ runs.
Produces the standard 256-bit (64 hex character) digest.
Install
pip install sm3hash
Usage
from sm3hash import sm3_hex, sm3_of_file
# text or bytes
assert sm3_hex("abc") == "66c7f0f462eeedd9d1f2d46bdc10e4e24167c4875cf2f7a2297da02b8f4ba8e0"
# bytes are hashed as-is
sm3_hex(b"abc")
# large files, streamed in 1 MiB chunks
sm3_of_file("big.iso")
sm3_of_file("big.iso", n_chunk=4 * 1024 * 1024)
API
| Function | Description |
|---|---|
sm3_hex(data) |
Digest a str (UTF-8 encoded) or bytes, returns hex string |
sm3_of_file(path, chunk=1 MiB) |
Digest a file by streaming, returns hex string |
Strings are encoded as UTF-8 before hashing. Pass bytes to control the
encoding yourself.
Performance
Pure Python, roughly an order of magnitude slower than hashlib.sha256 on the
same input. Fine for hashing tokens, small payloads and verifying signatures;
for bulk throughput consider a C-backed SM3 binding instead.
