引言

在数据传输和存储过程中，确保数据的完整性是非常重要的。MD5（Message Digest Algorithm 5）是一种广泛使用的哈希函数，它可以将任意长度的输入数据生成一个128位的散列值，用于验证数据的完整性。Python作为一种流行的编程语言，提供了多种方法来实现大文件的MD5校验。本文将详细介绍Python中高效大文件MD5校验的实现方法。

MD5算法简介

MD5算法是一种广泛使用的加密散列函数，由Ron Rivest设计。它能够对任意长度的输入数据生成一个128位的散列值。MD5散列值通常以32个十六进制数字表示，例如：`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
