什么是SHA1指纹? [英] What is a SHA1 fingerprint?

问题描述

我正在从 Google 获取 Google Play API 密钥，它要求输入 SHA1 指纹.我想知道什么是SHA1指纹?我也想知道这个API key是否可以在其他电脑上使用?

I am obtaining a Google Play API key from Google, and it is asking to enter SHA1 fingerprint. I want to know what is SHA1 fingerprint? I also wanted to know whether this API key can be used from another computer?

推荐答案

它是实现安全哈希算法"的标准 - 一种单向加密函数，可用作字节序列.2 个不同的字节序列不太可能产生相同的值(尽管并非不可能)

It is a standard for the implementation of a 'secure hash algorithm' - a one-way cryptographic function that can be used to act as a 'signature' of a sequence of bytes. It is very unlikely that 2 different byte sequences would produce the same value (though not impossible)

请注意，现在还有其他更强大的标准，例如SHA256 及更高版本.

Note that there are other, more robust standards out there these days e.g. SHA256 and beyond.
