如何在ruby中创建SHA1哈希？

Question

SHA Hash函数

Answer 1

require 'digest/sha1'
Digest::SHA1.hexdigest 'foo'

Answer 2

对于Base64编码的哈希,为了验证Oauth签名,我使用了

require 'base64'
require 'hmac-sha1'

Base64.encode64((HMAC::SHA1.new('key') << 'base').digest).strip

Answer 3

我创建了一个帮助器gem,它是一个sha1代码的简单包装器

require 'rickshaw'
> Rickshaw::SHA1.hash('LICENSE.txt')

 => "4659d94e7082a65ca39e7b6725094f08a413250a" 

> "hello world".to_sha1

 => "2aae6c35c94fcfb415dbe95f408b9ce91ee846ed"
