Configure ASP.NET Core Data Protection to Persist Keys To DbContext

PersistKeysToDbContext

dotnet add package Microsoft.AspNetCore.DataProtection.EntityFrameworkCore

Add using Microsoft.AspNetCore.DataProtection; to Startup.cs

builder.Services.AddDataProtection()
    .PersistKeysToDbContext<SampleDbContext>();

The preceding code stores the keys in the configured database. The database context being used must implement IDataProtectionKeyContext. IDataProtectionKeyContext exposes the property DataProtectionKeys

public DbSet<DataProtectionKey> DataProtectionKeys { get; set; } = null!;
