hi try something like this

C#

string signature = System.Security.Cryptography.FormsAuthentication.HashPasswordForStoringInConfigFile(concatenatedString;SHA1");

there is no need to convert it into base64 unless you want to store it in some readable form

Solution 6

string secretkey = "CD45FF96D6752A4D";

C#

string token = Convert.ToBase64String(Guid.NewGuid().ToByteArray());
        string sectoken = Convert.ToBase64String(Guid.NewGuid().ToByteArray());

var enc = Encoding.ASCII;
        HMACSHA256 hmac = new HMACSHA256(enc.GetBytes(secretkey));
        hmac.Initialize();

        byte[] buffer = enc.GetBytes(sectoken);
        string signature = BitConverter.ToString(hmac.ComputeHash(buffer)).Replace("-", "").ToLower();

change token and sectoken

I dont think that was difficult. Just change the syntax to C#. Here is the translated code

C#

string signature = rawurlencode(base64_encode(hash_hmac("sha1", concatenatedString, privateKey, true)));
