其中sha256对应的C#加密方法如下

///

/// 加密秘钥

/// 待加密的内容

///

StringBuilder sb = new StringBuilder();

for (int i = 0; i < retVal.Length; i++)

{

sb.Append(retVal[i].ToString("x2"));

}

return sb.ToString();

}

catch (Exception ex)

{

throw new Exception("GetSHA256HashFromString() fail,error:" + ex.Message);

}

}
