Hi all, I'm trying to understand if this chat has any legs, and what you all make of it? "Thunderbird can be plugged into PGP - which I have - and I can send emails encrypted by PGP WITH 4096 bit keys. Evolution does not support PGP. The other email client that supports PGP IS K-mail." Guy pushed back quoting: "Evolution supports both OpenPGP and S/MIME for secure messaging." https://www.lifewire.com/evolution-email-program-1164861 Answer went.... "when you create a pair of keys for GPG, one is a public key and the other is private key. You export you PUBLIC key to the people you wish to communicate with, so they'll use it to encrypt the emails sent to you, then you use your PRIVATE key to decrypt the email sent to you encrypted with your PUBLIC key - which must be available to anyone so they can encrypt emails sent to you. Your PRIVATE key is and should be SECRET. You use it to decrypt the emails sent to you encrypted with your PUBLIC key. You must provide your public key to anyone you communicate with, assuming they too have PGP or the open source GPG which is the same like PGP ECXEPT that GnuPG IS open source and free encryption unlike the MIT's PGP which is expensive. This kind of 2-key encryption-decryption system is called "assymetric encryption. You can ALSO use symetric encryption which uses just one key for both encryption and decryption using a password known only to you and the party you communicate with, but this symetric encryption is easy to break unlike assymetric encryption in which one key is used to encrypt messages or entire folders and another key used to decrypt messages or folders. The private key should be guarded very very well and stored on a removable medium like a pendrive or microSD card. The public key is part of your private key so one cannot work without the other. No one can break a 4096 bit key. So save and guard your private key on an USB flash drive. Without this key you won't be able to decrypt the emails or files/folders. Also I need to mention that GPG comes with every Linux distro unlike Windows. Linux authenticates packages with GnuPG keys of the developers, so it's preinstalled on Linux. You have to create a key pair and you're good to go. Make sure you choose the 4096 bit key length when setting up the GnuPG. ________________ Finally, I've been trying to import into Thunderbird on my iMac but it will not work. Is there a patch or anything I need to download for Thunderbird to help it actually transfer my Apple mboxes?
