Pretty Good Privacy (PGP) is a data encryption and decryption computer program that provides cryptographic privacy and authentication for data communication. PGP is often used for signing, encrypting, and decrypting texts, emails, files, directories, and whole disk partitions, and to increase the security of email communications.
How does the PGP works?
For the PGP encryption, public and private keys are used. The user on each end of the communication must have a PGP key. Each public key is bound to an email address. The sender will encrypt the message with the recipient’s public PGP key and the sender’s signature. When the recipient receives the message, they must use their passphrase (private key) in order to decrypt the message.
To use PGP for STEX email communication, go to the account settings and click "Activate":
Then you need to provide your Public Key in the required field and submit it to get the email with the activation link.
To complete the activation you need open the email and click on the ''activate now'' button. The email is encrypted. In order to open it, you can use a browser extension or set up a specialized mail client.
Congrats, the email encryption is activated.
