c# 生成SHA1加密字符串

 从网上找到的一种加密代码：

var enstr ="abcdefg"; var strRes = Encoding.Default.GetBytes(enstr); HashAlgorithm iSha = new SHA1CryptoServiceProvider(); strRes = iSha.ComputeHash(strRes); var enText = new StringBuilder(); foreach (byte iByte in strRes) { enText.AppendFormat("{0:x2}", iByte); } 

  

还有另一种SHA1加密，我用来做腾讯云签名：

HMACSHA1 hmacsha1 = new HMACSHA1(Encoding.UTF8.GetBytes(SecretKey)); byte[] rstRes = hmacsha1.ComputeHash(Encoding.UTF8.GetBytes(str)); string strs = Convert.ToBase64String(rstRes); return System.Web.HttpUtility.UrlEncode(strs);
