As far as I figured out:

If an application is not signed, it will not work.

Signing is taking an MD5 checksum from the application, and encrypting it with 
a private key, in sucha a way, you need one key to encrypt and another to 
decrypt (RSA. [The decryption key is a derivate from the encryption in
signing, in real encryption, it's the other way around])

The encrypted checksum (signature) is then pasted in after the program file,
and your app is signed.

Hope it was clear.
