How to Encrypt Messages with PGP

There are numerous ways, but the most popular encryption method in this digital era is PGP technology.

What is encryption? Simply it means turning a readable message into an unreadable form for other people other than the intended recipient.

The first step to securing your messages is installing the GPG software.

If you send a message using PGP, it will be converted into an unreadable format before transiting over the internet to the recipient.

How does the recipient read the encrypted message?

The recipient has a key that will decrypt the message to a readable format.

For data to be transited online, PGP uses symmetric and asymmetric keys for encryption purposes.

Why Is PGP So Popular Today?

Two primary factors make PGP popular.

The PGP encryption system was made available for free.

PGP uses symmetric encryption and public-key encryption that allows users unknown to each other to send encrypted emails to one another.

There are numerous software applications that you can download based on the purpose of your PGP encryption.

Outlook with gpg4o: it is one of Windows users’ best solutions as it easily integrates with outlook 2010 and 2016.

PGP works by generating a random session key.

The key is used to encrypt and decrypt the message content.

The recipient’s public key is used to encrypt the session key.

The public key is unique but can be shared among users.

An excellent example of a public key is your email address, as it does not change.

Encryption and Decryption Process

The sender encrypts the raw file using the public key.

After the recipient receives the encrypted text, they decrypt the session key, and in turn, it decrypts the message.

Having encryption software is a requirement, especially among business people.

It ensures that your private information remains private and is only accessible to the intended recipient.
