Library to partialy hash files.
Installation
pip install partialhash
Usage
# from examples/usage.py
import binascii
import partialhash
path = "examples/random.data"
# sha256 hash of full file
digest = partialhash.compute(path) # file path or file like object
print(binascii.hexlify(digest))
# sha256 hash of first 1024 bytes
digest = partialhash.compute(path, length=1024)
print(binascii.hexlify(digest))
# sha256 hash, skipping the first 512 bytes
digest = partialhash.compute(path, offset=512)
print(binascii.hexlify(digest))
# sha256 hash of seed + file data
digest = partialhash.compute(path, seed=b'seeddata')
print(binascii.hexlify(digest))
# sha256 hash of 256 byte sample with given seed
# which data is sampled depends on given seed
digest = partialhash.sample(path, 256, seed=b'seeddata')
print(binascii.hexlify(digest))
# sha256 hash of three 256 byte samples with given seed
# sample data will not overlap until sample size exceeds file size
digest = partialhash.sample(path, 256, sample_count=3, seed=b'seeddata')
print(binascii.hexlify(digest))1 maintainer
