Question

这是一个C＃代码：

byte[] pb = System.Text.Encoding.UTF8.GetBytes(policy.ToString());

// Encode those UTF-8 bytes using Base64
string policyB = Convert.ToBase64String(pb);

// Sign the policy with your Secret Key using HMAC SHA-1.
System.Security.Cryptography.HMACSHA1 hmac = new System.Security.Cryptography.HMACSHA1();
hmac.Key = System.Text.Encoding.UTF8.GetBytes(secretKey);

byte[] signb = hmac.ComputeHash(System.Text.Encoding.UTF8.GetBytes(policyB));

string signature = Convert.ToBase64String(signb);

如何在Ruby on rails上做同样的事情？更具体地说，我需要知道从string获取字节的函数，base64对它们进行编码并计算hmac hash。

Answer 1

不确定完全是否相同，但它对我有用：

@policy = ActiveSupport::Base64.encode64s(@policy)

# Sign policy with secret key
digest = OpenSSL::Digest::Digest.new('sha1')
@signature = ActiveSupport::Base64.encode64s(OpenSSL::HMAC.digest(digest, secretKey, @policy))

Answer 2

我会再试一次。

有一些用于ruby / rails的HMAC库可能会使这更简单： http://auth-hmac.rubyforge.org/
