MD5是否仍然足以唯一地识别文件？ [英] Is MD5 still good enough to uniquely identify files?

问题描述

MD5哈希一个文件仍然被认为是一个足够好的方法来唯一标识它，因为所有的MD5算法和安全问题的破坏等？安全性不是我最关心的问题，但唯一标识每个文件是。

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？

Any thoughts?

推荐答案

是的。从安全角度来看，MD5已经被彻底打破，但意外碰撞的可能性仍然很小。请确保这些文件不是由您不信任的人创建的，并且可能具有恶意意图。

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.
