To install Russian national standard cryptographic algorithms, run the following command in the Nuget Package Manager Console:

PM> Install-Package OpenGost.Security.Cryptography

After package installation, enable cryptographic services:

using OpenGost.Security.Cryptography;

OpenGostCryptoConfig.ConfigureCryptographicServices();
