RFC 4226 (HOTP) - HMAC-Based One-Time Password Generator.

NOTE - CRITICAL CHANGE!

This library is not compatible with TOTP (Time-based One-Time Password) anymore! Please check the ISSUE #1 (FIXED) - https://github.com/sim756/sim756.HOTP/issues/1

For TOTP, pelase use the following TOTP library

NuGet - sim756.TOTP - https://www.nuget.org/packages/sim756.TOTP <br> GitHub - sim756.TOTP - https://www.github.com/sim756/sim756.TOTP

// Example 1: Using KeyString property and default counter (0)
var generator = new HOTPGenerator { KeyString = "QWERTYUIOPASDFGH" };
string hotp = generator.Compute(0);
// Example 2: Using KeyString property and a specific counter (e.g., 2)
var generator2 = new HOTPGenerator { KeyString = "QWERTYUIOPASDFGH" };
string nextHotp = generator2.Compute(2);
// Example 3: Using object initializer for KeyString and Length, and default counter (0)
var generator3 = new HOTPGenerator
{
    KeyString = "QWERTYUIOPASDFGH",
    Length = 6
};
string hotp3 = generator3.Compute(0);
