LZNT1

Python implementation of LZNT1 compression/decompression.

Note that the compression algorithm is not perfect, but compressed data can be decompressed by RtlDecompressBuffer.

How to use

Install

pip install lznt1

Compress / decompress

>>> import lznt1
>>> compressed = lznt1.compress(data)
>>> decompressed = lznt1.decompress(compressed)

Test

C:\Users\you\Desktop\ln>python test.py lznt1.py
