< p > Bob wants to send a sensitive message to Alice. Bob intends to send his sensitive message to Alice through various means, for example on Teams, Discord or even on Wickr. However Bob knows that these service providers will never respect his privacy, they will always spy on Bob's conversation:< / p >
< img src = "1.png" class = "imgRz" >
< p > Bob then decides that noone other than Alice will be able to decrypt his message. So, Bob decides to use PGP encryption, to be able to send a sensitive message to Alice < b > on any platform< / b > he wishes, because he knows that only Alice will be able to decrypt it: < / p >
< / br >
< img src = "2.png" class = "imgRz" >
< p > Why should you even care about PGP ? Simple, you only want one person to be able to read your message, so you use PGP. You can use it when you do not trust the chat platform you are using, or the email provider, or any other form of communication with text. PGP gives you a simple way of encrypting your messages with others' public key, so that way you're sure that noone can read your messages.< / p >

We need to generate a lot of random bytes. It is a good idea to perform
some other action (type on the keyboard, move the mouse, utilize the
disks) during the prime generation; this gives the random number
generator a better chance to gain enough entropy.
