What is PGP and how does it work?
PGP is a cryptographic method that lets people communicate privately online. When you send a message using PGP, the message is converted into unreadable ciphertext on your device before it passes over the internet. Only the recipient has the key to convert the text back into the readable message on their device.

How does an encryption key work?
An encryption key is typically a random string of bits generated specifically to scramble and unscramble data. Encryption keys are created with algorithms designed to ensure that each key is unique and unpredictable. The longer the key constructed this way, the harder it is to break the encryption code.
What types of PGP keys are there?
PGP uses four kinds of keys: session keys, public and private keys, and passphrase generated keys. Public / private key pairs are the most expensive to generate. Since the security of the system depends on protecting private keys, these are encrypted using a passphrase system.
What is the purpose of encryption software?
Encryption software is software that uses cryptography to prevent unauthorized access to digital information. Cryptography is used to protect digital information on computers as well as the digital information that is sent to other computers over the Internet.
