The Pretty Good Privacy (PGP) format is an encryption standard originally developed by Phil Zimmermann and currently maintained by Broadcom. It is primarily used for securing electronic communications, verifying digital signatures, and protecting sensitive data stored on local disks or transmitted over insecure networks. Although modern implementations typically adhere to the OpenPGP specification, this legacy format remains an established tool for ensuring data confidentiality and authenticity in various enterprise environments.

}
Go
