SHA1 碰撞演示/示例 [英] SHA1 collision demo / example

问题描述

这个问题类似于这个，但那个问题只引用了 MD5 碰撞演示.

This question is similar to this, but that one only references MD5 collision demos.

到目前为止，是否有任何已知的任意消息的实际 SHA1 冲突对?

Are there any actual SHA1 collision pairs of arbitrary messages known so far ?

我想用这些来测试各种软件产品(我自己的和一些第三方的)如何处理它.

I'd like to use these to test how various software products (my own one and some third party) deal with it.

进行一些 Google 搜索只发现了非常突出的 MD5/SHA0 冲突以及有关创建 SHA1 冲突的方法的一些提示，但我无法获得任何示例.

Doing some Google searches only turned up the oh-so prominent MD5 / SHA0 collisions and some hints on an approach to creating SHA1 collisions but I could not get my hands on any examples.

推荐答案

第一个已知的碰撞现已发布在 https://粉碎.它/
