Beware of a possible misunderstanding here: encryption is done with the *public* key. It is decryption which requires the private key. So you can easily encrypt something with any of the (possibly many) public keys from your key ring. > Thank you Vincent for your detailed answer, Welcome ! > which is way over my head. Don't worry, I was tossing some ideas to maybe save you from disclosing your entire file to someone else (by only exchanging the encrypted session key rather than the whole file). But I 100% deffer to anyone knowledgeable about gnupg itself for whether anything I suggest is actually possible, and how to do it. > I really should look into the internals of file encryption one day … Besides on-line sources like wikipedia or youtube (computerphile channel has several crypto-related videos), I found the following book to be especially enlightening (...from a crypto-unrelated developer perspective anyway): https://www.schneier.com/books/cryptography-engineering/ Regards, -- Vincent Pelletier GPG fingerprint 983A E8B7 3B91 1598 7A92 3845 CAC9 3691 4257 B0C1 _______________________________________________ Gnupg-users mailing list Gnupg-users@gnupg.org http://lists.gnupg.org/mailman/listinfo/gnupg-users
