An ASP.NET Core library for generating and validating one time passwords for authenticator apps.
Forked from the original at https://github.com/damirkusar/AspNetCore.Totp to solve the issue that Google Image Charts has been deprecated.
```
Install-Package AspNetCore.TotpGenerator
```
Use TotpSetupGenerator class to generate the QR Code to show to user.
Use TotpGenerator class to generate a one time password like the Google authenticator does.
Use TotpValidator class to validate the one time password supplied by the user.
