I have the following C# code in a .NET application I'd like to do the same thing in a Power Automate Flow.
Is that possible?
private string GetSignature(string signtext, string privateKey)
{
System.Text.ASCIIEncoding encoding = new System.Text.ASCIIEncoding();
byte[] keybytes = encoding.GetBytes(privateKey);
byte[] signbytes = encoding.GetBytes(signtext);
HMACSHA256 hmacsha256 = new HMACSHA256(keybytes);
return EncodeTo64(ByteToString(hmacsha256.ComputeHash(signbytes)).ToLower());
}
private string EncodeTo64(string toEncode)
{
byte[] toEncodeAsBytes = System.Text.ASCIIEncoding.ASCII.GetBytes(toEncode);
string returnValue = System.Convert.ToBase64String(toEncodeAsBytes);
return returnValue;
}
The HMACSHA256 class is in the .NET System.Security.Cryptography namespace.
