In cryptography and computer security, a self-signed certificate is an identity certificate that is signed by the same entity whose identity it certifies. This term has nothing to do with the identity of the person or organization that actually performed the signing procedure. In technical terms a self-signed certificate is one signed with its own private key.
What this is supposed to do is verify that you are actually connecting or receiving the cert from who you are connecting to through SSL.

So as I understand it you 'sign' a cert with a private key, and you decrypt with a private key

But what is the difference between a signed cert and an encrypted cert?   Possibly a hash or check sum ?

The only difference is the value of the purpose field in the certificate. The issuer of the certificate chooses for what purpose the certificate is created.
