## Development Environment
We've enabled `AddDevelopmentEncryptionAndSigningCertificate` by default on development environment, It registers (and generates if necessary) a user-specific development encryption/development signing certificate. This is a certificate used for signing and encrypting the tokens and for **development environment only**.

`AddDevelopmentEncryptionAndSigningCertificate` cannot be used in applications deployed on IIS or Azure App Service: trying to use them on IIS or Azure App Service will result in an exception being thrown at runtime (unless the application pool is configured to [load a user profile](https://learn.microsoft.com/en-us/iis/manage/configuring-security/application-pool-identities#user-profile)).
To avoid that, consider creating self-signed certificates and storing them in the X.509 certificates storage of the host machine(s). This is the way we do it in production environment.

## Production Environment
We've disabled `AddDevelopmentEncryptionAndSigningCertificate` in production environment and tried to setup signing and encrypting certificates using `authserver.pfx`.
We've disabled `AddDevelopmentEncryptionAndSigningCertificate` in the production environment and tried to setup signing and encrypting certificates using `openiddict.pfx` file.
You can use the `dotnet dev-certs https -v -ep authserver.pfx -p 00000000-0000-0000-0000-000000000000` command to generate the `authserver.pfx` certificate.
You can use the `dotnet dev-certs https -v -ep openiddict.pfx -p 00000000-0000-0000-0000-000000000000` command to generate the `authserver.pfx` certificate.
> `00000000-0000-0000-0000-000000000000` is the password of the certificate, you can change it to any password you want.
