Hello Ash, I just happened to be looking through the GPG USERS message digest and saw this post. Excited, I realized I knew the answer! Welcome to GNU Privacy Guard! Your secret keys are able to recreate the public key, but not vice-versa. So if you need to share a public key with someone, export your public key and share it or put it on biglumber.com or the key server. Your secret key should always be backed up and never shared... it is all you need, you don't need to "back-up" your public key (which is worthless without the secret key to go with it on your computer(s)). I hope this helps you. - -Steve -----BEGIN PGP SIGNATURE----- Version: GnuPG/MacGPG2 v2.0.18 (Darwin) Comment: GPGTools - http://gpgtools.org Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iEYEARECAAYFAlFn0W4ACgkQAS9dxxA237qnDwCffAfRDdDJtu4Zigg1pXPEx6Xp LeUAnRppVcHNTtqviwG02ti2SnPNmSDm =C7Uf -----END PGP SIGNATURE-----
