问题描述
所以现在有很多不同的服务,Google API、Twitter API、Facebook API 等等.
每个服务都有一个 API 密钥,例如:
AIzaSyClzfrOzB818x55FASHvX4JuGQciR9lv7q
所有密钥的长度和它们包含的字符都不同,我想知道生成 API 密钥的最佳方法是什么?
我不是要求一种特定的语言,只是创建密钥的一般方法,它们应该是对用户应用程序细节的加密,还是散列,还是随机字符串的散列等.我们应该担心关于哈希算法(MSD、SHA1、bcrypt)等?
编辑:我和几个朋友谈过(电子邮件/推特),他们建议只使用去掉破折号的 GUID.
这对我来说似乎有点 hacky,希望能得到更多的想法.
推荐答案
使用专为密码学设计的随机数生成器.然后base-64编码数字.
这是一个 C# 示例:
var key = new byte[32]; using (var generator = RandomNumberGenerator.Create()) generator.GetBytes(key); string apiKey = Convert.ToBase64String(key);
问题描述
So with lots of different services around now, Google APIs, Twitter API, Facebook API, etc etc.
Each service has an API key, like:
AIzaSyClzfrOzB818x55FASHvX4JuGQciR9lv7q
All the keys vary in length and the characters they contain, I'm wondering what the best approach is for generating an API key?
I'm not asking for a specific language, just the general approach to creating keys, should they be an encryption of details of the users app, or a hash, or a hash of a random string, etc. Should we worry about hash algorithm (MSD, SHA1, bcrypt) etc?
Edit: I've spoke to a few friends (email/twitter) and they recommended just using a GUID with the dashes stripped.
This seems a little hacky to me though, hoping to get some more ideas.
推荐答案
Use a random number generator designed for cryptography. Then base-64 encode the number.
This is a C# example:
var key = new byte[32]; using (var generator = RandomNumberGenerator.Create()) generator.GetBytes(key); string apiKey = Convert.ToBase64String(key);
