Script finished, now what?

[RCasatta]

I run the script and it finished producing result.pub and result.sec
I changed line https://github.com/Valodim/pgp-vanity-keygen/blob/master/vanity.c#L195 to match my UID
if I try to import gpg --import result.pub in my keyring I got:

gpg: key 707FBEEF: no valid user IDs
gpg: this may be caused by a missing self-signature

if I try to import gpg --import result.sec in my keyring I got:

gpg: key 1800EBBE: secret key imported
gpg: key 1800EBBE: no valid user IDs
gpg: this may be caused by a missing self-signature

then I try to self sign gpg -u 1800EBBE --sign result.pub

gpg: key 1800EBBE: secret key without public key - skipped
gpg: skipped "1800EBBE": secret key not available
gpg: signing failed: secret key not available

Trying to re-import the pub key with gpg --allow-non-selfsigned-uid --import result.pub

gpg: key 1800EBBE: accepted non self-signed user ID "Pippo"
gpg: key 1800EBBE: public key "Pippo" imported
gpg: Total number processed: 1
gpg:               imported: 1  (RSA: 1)

if I re-try to sign with gpg -u 1800EBBE --sign result.pub

gpg: skipped "1800EBBE": unusable secret key
gpg: signing failed: unusable secret key

I've started a README.md in my fork with instructions for using the keys: https://github.com/osresearch/pgp-vanity-keygen/blob/master/README.md
