Video: PGP Encryption
PGP stands for “Pretty Good Privacy”. It’s an encryption program that provides cryptographic privacy and authentication for data communication.
PGP is used for signing, encrypting, and decrypting texts, e-mails, files, directories, and whole disk partitions and to increase the security of e-mail communications.
It comes as an optional add-on with most managed file transfer solutions.
