ASP.NET MVC password validation with hash -

so want add custom hash password, got stuck because own validation

my model:

public class ms_user {     [required(errormessage = "please input login email")]     [datatype(datatype.emailaddress)]     public object user_id { get; set; }      [required(errormessage = "please input password")]     // validation @ least 1 uppercase & 1 number, password lenght must greater 6 , lower 12, no special character     [regularexpression(@"^(?=.*\d)(?=.*[a-z])[a-za-z0-9](.{6,12})$", errormessage = "error, wrong password format")]      public object password { get; set; } } 

sample:

password inputed : admin123 // pass validation

hashedpassword output: l92vi3c2af7oftgy7jqyjkr8isyxef8pioqvmzjrn6rnrct6w6uudzv0yrcoudppxnc69gj2j4igxzwh1wrz9c19abn4uwksqx8d0txa+0ivxjavzoksaewpqm56gy/l:9kzqeh3nb9apjy81v/fvfu // after hashed password,

my project pass password validation, on db.savechanges(); return error, because password validation

is there solution?? prefer not add javascript validation...
