散列冲突的例子? [英] Examples of Hash-Collisions?

问题描述

出于演示目的，有哪些字符串在散列时发生冲突的示例?MD5 是一个相对标准的散列选项，所以这就足够了.

For demonstration-purposes, what are a couple examples of strings that collide when hashed? MD5 is a relatively standard hashing-option, so this will be sufficient.

请注意，尽管您的问题要求冲突的字符串"，但 MD5 是在 二进制 数据上定义的，因此字符串"的正常文本含义并不真正适用.允许您对文本数据进行 MD5 散列的语言和库通常意味着以指定的编码对字符串进行编码，然后对结果进行散列."

Note that although your question asked for "strings" which collide, MD5 is defined over binary data, so the normal text meaning of "string" doesn't really apply. Languages and libraries which allow you to take the MD5 hash of text data usually mean "encode the string in a specified encoding, then hash the result."
