333

English | 中文

字节、字符串与文件哈希，附带低成本的文件比对。

安装

pip install 333

用法

from p333 import compare_files, hash_bytes, hash_file

hash_bytes("abc")                       # blake2b
hash_bytes(b"abc", n_algo="sha256")
hash_file("big.iso")                    # 1 MiB 分块
hash_file("big.iso", n_algo="md5", n_chunk=4 << 20)
compare_files("a.bin", "b.bin")         # True / False

说明

包名以数字开头，导入名是 p333。支持 blake2b（默认，最快）、sha256、sha1、md5；文件按块流式读取。compare_files 先比大小，大小不同一个 stat 就返回，不读内容。

English

Hashing for files and bytes across several algorithms.

Install

pip install 333

Usage

from p333 import compare_files, hash_bytes, hash_file

hash_bytes("abc")                       # blake2b
hash_bytes(b"abc", n_algo="sha256")
hash_file("big.iso")                    # 1 MiB 分块
hash_file("big.iso", n_algo="md5", n_chunk=4 << 20)
compare_files("a.bin", "b.bin")         # True / False

Notes

The distribution name starts with a digit, so the import name is p333. Algorithms: blake2b (default, fastest), sha256, sha1, md5. compare_files compares sizes first, so unequal files cost one stat instead of two full reads.
