As an AI language model, I can suggest the following to help you encrypt the password using PasswordHasher<> in C#.

First, you need to add the following namespaces to your code: csharp

using Microsoft.AspNetCore.Identity;
using Microsoft.Extensions.DependencyInjection;

Then, in the ConfigureServices method of your Startup.cs file, add the following line to register the PasswordHasher<> service: csharp

services.AddScoped<IPasswordHasher<ApplicationUser>,PasswordHasher<ApplicationUser>>();

Here, ApplicationUser is the name of your user model.

Now, in your user creation method, you can use the PasswordHasher<> service to hash the user password like this: csharp

var passwordHasher = 
serviceProvider.GetService<IPasswordHasher<ApplicationUser>>();

var hashedPassword = passwordHasher.HashPassword(user, plainTextPassword); Here, user is an instance of your user model, and plainTextPassword is the password entered by the user.

You can then set the hashed password in the user model and save it to your context.

Hope this helps!
