I am calculating a signature over private keypair. How the data to be

Coded count, encrypted dsa x, encrypted sha1 hash (20 octets) included to
the signed data? Can someone clarify this?
OpenPGP does not support the notion of calculating a signature over a
private keypair.
Generally a signature is done on a public key as part of a certification
of that key that will be publicly available. Signing a private key
would not be useful because the private key material is normally not
shared with others, so signature verification would be impossible.
