Below my code where i'm generating bearer token key

bc2589931f6f7182d53d918fe7c29f387612179d74a45b17a872967433a6d77f //wrong token
62A5B9C82E7C195CF65DDFB4FCE26576F51ACB2DB6AB1F496C424AC7365E0A8 //wrong tokencorrect token

why m i getting wrong token generated from below code?

public string ComputeSha256Hash(string rawData)
{

using (SHA256 sha256Hash = SHA256.Create())
{

byte[] bytes = sha256Hash.ComputeHash(Encoding.UTF8.GetBytes(rawData));
String sty= Convert.ToBase64String(bytes);

//Convert byte array to a string
StringBuilder builder = new StringBuilder();
for (int i = 0; i < bytes.Length; i++)
{
builder.Append(bytes[i].ToString("x2"));
}

Console.WriteLine(builder.ToString());
Console.ReadKey();

return builder.toString();
}
}

RE: Authorization bearer token need to be generated as a sha256 hash of base64 encoded json payload and secret key

Hi,

The token requirement varies with the client. I worked on an integration with WEB API where the token was generated in the following format (key + secret + unixtimestamp)

==============

var apiKey = "<keyvalue>";

var apiSecret = "<secret>";

var unixTimestamp = (Int32)(DateTime.UtcNow.Subtract(new DateTime(1970, 1, 1))).TotalSeconds;

System.Text.ASCIIEncoding encoding = new System.Text.ASCIIEncoding();

byte[] sinByte = encoding.GetBytes(apiKey + apiSecret + unixTimestamp);

HMACSHA256 hmacsha256 = new HMACSHA256();

hmacsha256.ComputeHash(sinByte);

byte[] hashmessage = hmacsha256.ComputeHash(sinByte);

var signature = ByteToString(hashmessage);

==========

Hope this helps.
