为什么在同一密码上由两个不同的服务器产生不同的“散列”

Question

I have a web aplication where I can create Tecnico

TecnicoController (application web)

        $tecnico = new Tecnico;
        $tecnico->idTecnico = Input::get('idtecnico');
        $tecnico->Nombre = Input::get('nombre');
        $tecnico->Apellido = Input::get('apellido');
        $tecnico->Telefono = Input::get('telefono');
        $tecnico->Contrasena = Hash::make(Input::get('idtecnico'));  //<--- hash of my pass, eg pass: 12 -> hash: $12345abc
        $path = public_path().'/tecnico';
        $fotoPerfil = Input::file('imagen');
        $fotoPerfil->move($path, Input::get('idtecnico'));
        $tecnico->Foto ='/tecnico/'.$tecnico->idTecnico;
        $tecnico->save();

Also I have a different project, that works as a server to access the database from a mobile application. A Tecnico from your cell phone can access your account by entering a contrasena (password) and idTecnico(id)

TecnicoController (server)

        $idUnico = Input::get('idUnico');
        $contrasena = Hash::make(Input::get('contrasena')); //<--- hash of my pass: eg pass: 12 -> hash: $146435gzc (change)
        $tecnico = DB::table('Tecnico')->where('idTecnico', $idUnico)->where('Contrasena',  $contrasena)->first();

The problem happens when you enter the password from the server. The Hashin creates a different value that exists in the database (when creating a Tecnico).

How I can get the same hash value that is in the database?

Unfortunately you can't do this easily in a query, your best bet would be to grab the user and then compare the password, like so.

$idUnico = Input::get('idUnico');
$tecnico = DB::table('Tecnico')->where('idTecnico', $idUnico)->first();

if($tecnico) {
    if(Hash::check(Input::get('contrasena'), $technico->Contrasena)) {
        // passwords are the same
    }
}
