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

问题描述

我正在从Google获得Google Play API密钥，并且要求输入SHA1指纹.我想知道什么是SHA1指纹?我还想知道天气可以从另一台计算机/PC使用此API密钥吗?

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 weather this API key can be used from another computer/pc?

推荐答案

这是实现安全哈希算法"的标准-一种单向加密功能，可以用作以下项的签名"字节序列. 2个不同的字节序列产生相同值的可能性很小(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，目前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.
