Pretty Good Privacy (PGP) Encryption
When the message is sent, the public key of the receiver is used, and then the receiver uses their private key to decrypt the message.
The practice is used in darknet markets where vendors and sellers use the encryption method to protect the confidentiality of information they send between each other.
The average internet user may also find PGP useful for communicating online, as the reality of government surveillance continues to loom over citizens’ everyday lives.
On a broader level, PGP is used in instances where sensitive material is being exchanged between two parties.
This includes conversations about classified material between journalists and whistleblowers, as well as intergovernmental communications between federal entities.
Dark Web News has published a comprehensive guide here that outlines the importance of PGP and walks readers through the process of setting one up.
