I am often asked in the process of communication, what is this PGP program? I try to explain to everyone that this is the most powerful cryptographic program designed to encrypt your letters in the first place. …And the main advantage of this program is that there is no need to share a password for a person to receive or send a message for someone. The key file is divided into two parts, Public (PUB) and Private (SEC). You just need to transfer the Public key to him in any way. It doesn't matter which one. Or simply send him a text block of the key, or send the key to a special server so that anyone can get it from there, or transfer the key on a floppy disk. This variant of cryptography is called "Public Key Cryptography". The man encoded a message for me with my key and after that, even himself, could not gain access to the letter, but why would he? He wrote it... And I still had the second half of the key, with which I could read messages encoded with my Public Key...Katie Nickol, admin old.pgpru.com[1]
