Custom setter for C# model

Question

I don't know how to make custom setter for C# data model. The scenario is pretty simple, I want my password to be automatically encrypted with SHA256 function. SHA256 function works very well (I've used in in gazillion of projects before).

I've tried couple of things but when I run update-database it seems it's doing something recursively and my Visual Studio hangs (don't send error). Please help me understand how to make passwords be encrypted by default in model.

Code with what I've already tried

public class Administrator
{
    public int ID { get; set; }
    [Required]
    public string Username { get; set; }
    [Required]
    public string Password
    {
        get
        {
            return this.Password;
        }

        set
        {
            // All this code is crashing Visual Studio

            // value = Infrastructure.Encryption.SHA256(value);
            // Password = Infrastructure.Encryption.SHA256(value);
            // this.Password = Infrastructure.Encryption.SHA256(value);
        }
    }
}

Seed

context.Administrators.AddOrUpdate(x => x.Username, new Administrator { Username = "admin", Password = "123" });

You need to use a private member variable as a backing-field. this allows you to store the value separately and manipulate it in the setter.

Good information here

public class Administrator
{
    public int ID { get; set; }

    [Required]
    public string Username { get; set; }

    private string _password;

    [Required]
    public string Password
    {
        get
        {
            return this._password;
        }

        set
        {  
             _password = Infrastructure.Encryption.SHA256(value);                
        }
    }
}
