Step 3: The sender passes along their session key, and the recipient can use their private key to decrypt and read the message. This public key is associated with the individual, and they can share it with anyone they wish to receive messages from. Step 2: This session key is encrypted using the recipient’s public key.Step 1: PGP generates an extremely complex single-use random session key that cannot be guessed.This both ensures the message gets to where it needs to go, and that the recipient is the only one who can decrypt the message.Īt the highest technological level, PGP encryption works in a three-step process: Once the receiver gets the email, they’ll decrypt it using their private key - an encryption key that is only known by one user. When a user wants to send a private email or message, they’ll encrypt it using the receiver’s public key - an encryption key that’s known to everyone. On a technical level, PGP encryption protects data by using a combination of public keys, private keys and session keys. In order to fully understand PGP encryption, we will look at it from a technical perspective and provide a practical analogy. PGP encryption works by scrambling, or encrypting, a message in a way that makes it unreadable to anyone who doesn’t have a way to decode it. In an age where cyber threats lurk around every virtual corner, this type of encryption is an essential tool for anyone who wants guaranteed privacy in their digital communications. Cybercriminals can easily intercept messages and access email accounts, and PGP ensures that the user’s information remains secure. PGP encryption is most commonly used for sending and receiving confidential emails. First developed in 1991, this technology has become one of the most popular encryption methods on the market due to its security and accessibility. PGP is an encryption system that’s used to safely send sensitive or private information. In this article we will detail the basics of PGP encryption: what it is, ways you can use it and if this technology is right for you. By coordinating and sharing virtual keys, email senders and receivers can ensure their information stays private and secure. PGP is an encryption system that scrambles your data, making it unreadable to anyone who doesn’t have the means of decoding it. To guarantee your information is safe from prying eyes, you need Pretty Good Privacy (PGP) encryption. Most people would answer that question with a resounding “no” - but unfortunately, in this modern technological age it’s far too easy for cybercriminals to gain access to your email accounts or the messages themselves. Are you OK with a stranger reading your emails?
