I have solve it!:

public function cryptMyPass($plaintext){

$password = '#D-$1gnD3skT0p!#';
$method = 'AES-128-CBC';

// Must be exact 32 chars (256 bit)
$password = substr(hash('sha512', $password, true), 0, 32);

// IV must be exact 16 chars (128 bit)
$iv = chr(0x0) . chr(0x0) . chr(0x0) . chr(0x0) . chr(0x0) . chr(0x0) . chr(0x0) . chr(0x0) . chr(0x0) . chr(0x0) . chr(0x0) . chr(0x0) . chr(0x0) . chr(0x0) . chr(0x0) . chr(0x0);

// av3DYGLkwBsErphcyYp+imUW4QKs19hUnFyyYcXwURU=
$encrypted = base64_encode(openssl_encrypt($plaintext, $method, $password, OPENSSL_RAW_DATA, $iv));

return $encrypted;
}

If you are using a hash function you ahould take into account that in some algorithms, different inputs may get the same output, in your case, different passwords may get hashed into the same value and be undifferentiable due to the hash function not being reversible
