Using GPG to encrypt files : exchange

Using GPG to encrypt files : exchange 






But what do you do if you want to be able to exchange
encrypted files with someone else and both of you be able to decrypt them?





1)  Copy your public keys to a public key server on 
the Internet.



gpg --keyserver hkp://subkeys.pgp.net --send-key key_ID 



gpg --keyserver hkp://subkeys.pgp.net --send-key 9DF54AB2 






key ID is: 

gpg --fingerprint key_owner_email 













2) You can also just directly exchange keys between systems. 




a)

gpg --export --armor key_owner_email > public_key_filename 



gpg --export rtracy@openSUSE > gpg.pub 





b)

Each user can then copy their key file to the other users. 


scp gpg.pub student@fedora: 





c)

Once this is done, each user should import the other users’ public 
keys into their GPG keyring using the 



gpg --import public_key_filename 



pg --import gpg.pub
