A .Net Core Data Protection provider to persist keys to Sql Server

The primary public use of this library will be via the PersistKeysToSqlServer() IDataProtectionBuilder extension method.

Usage: In your database context, implement IDataProtectionContext and add a DbSet property.

    public class ApplicationDbContext : IDataProtectionContext
    {
        public DbSet<DataProtectionKey> DataProtectionKeys { get; set; }
    ...
    }

In Startup.cs's ConfigureServices method, add a service to provide the IDataProtectionContext: services.AddTransient<IDataProtectionContext, ApplicationDbContext>();

Also in your startup's ConfigureServices method, when configuring DataProtection, you can now use PersistToSqlServer to persist your keys to a Sql Server database. You will need to provide the

Example:

  services.AddDataProtection()
      .PersistKeysToSqlServer(() => services.BuildServiceProvider().GetRequiredService<IDataProtectionContext>())
      .ProtectKeysWithCertificate(dataProtectionCert)
      .SetApplicationName("<AppName>")
      .SetDefaultKeyLifetime(TimeSpan.FromDays(10))
      .UseCryptographicAlgorithms(encryptionSettings);
