encrypting username in asp.net mvc5 login

Question

I want to encrypt the username for the login of an asp.net mvc5 site. When the controller calls var result = await UserManager.CreateAsync(user,model.Password); to register a new user, I get an error telling me

User name abc/12&3== is invalid, can only contain letters or digits.

I'm guessing I cannot make this function take these non-alphanumeric values, so how can I make an AES encrypted value fall within the guidelines?

Thanks, Dave K.

Answer 1

You seem to have found a way to hack around this but the real problem is just that you need to change the user validator:

UserManager.UserValidator = new UserValidator<ApplicationUser>(UserManager) 
  {
    AllowOnlyAlphanumericUserNames = false,
  };
