MD5 是否仍然足以唯一标识文件? [英] Is MD5 still good enough to uniquely identify files?

问题描述

考虑到 MD5 算法的所有破坏和安全问题等，MD5 散列文件是否仍然被认为是一种足够好的方法来唯一标识它?安全性不是我在这里的主要关注点，但唯一标识每个文件才是.

Is MD5 hashing a file still considered a good enough method to uniquely identify it given all the breaking of MD5 algorithm and security issues etc? Security is not my primary concern here, but uniquely identifying each file is.

有什么想法吗?

推荐答案

是的.从安全角度来说，MD5 已经完全被破解了，但是意外碰撞的概率还是微乎其微.请确保文件不是由您不信任的人创建的，并且可能具有恶意.

Yes. MD5 has been completely broken from a security perspective, but the probability of an accidental collision is still vanishingly small. Just be sure that the files aren't being created by someone you don't trust and who might have malicious intent.
