GPG Data, Secret Key but no Public Key?

Well, I recently got f****d by formatting, but forgetting to copy the directory I moved everything into to save onto my pen drive, but I did manage to keep my encrypted data for GPG.

The problem is I only have the secret key for the data, and not my public key... is there an option to recreate the public key from the secret key, or a way to get it to decrypt the files without a public key? Or am I screwed yet again?

I REALLY need some of the data in these files, so any help would be greatly appreciated

I'm having trouble understanding how you could still have the secret key but not the public key. What do you get if you open a terminal and issue the command: gpg --list-keys?

I formatted. I forgot to export my public key and only exported my secret key when backing stuff up. Make sense now?

You can generate a public key from a secret key, but not the other way around (so it sounds like you're in luck that you saved the right key).

To generate your public key in a text form suitable for sending to others, use:
gpg --armor --export <your email or gpg user name> >> <file to output the key to>

To generate your public key in binary from, use:
gpg --output <file to output the key to> --export <your email or gpg user name>

gpg: WARNING: nothing exported
I've tried almost everything, but I can't get it to export the public key....

"gpg --list-secret-keys" has my secret key there, and "gpg --list-keys" has nothing, as I assumed...

Any other ideas?

HAHA!!! Got it.

The development version of GPG imports both secret and public keys when importing a secret key. I am able to decrypt my files now and everything is looking much much better
