It is a system based on well-understood cryptographic building blocks. OpenPGP supports the secure delivery of files and messages between a sender and a recipient as well as verification of the sender. OpenPGP is an outgrowth of the ["Pretty Good Privacy (PGP)"](https://en.wikipedia.org/wiki/Pretty_Good_Privacy) encryption program and has many widely used and [interoperable implementations](interop_section). +With OpenPGP, you can: + +- [Encrypt](encryption_chapter) and [decrypt](decryption_chapter) messages +- [Sign](signing_data) and [verify](verification_chapter) data +- [Issue certifications and examine statements](certifications_chapter) about keys and identities, similar to the role of a Certificate Authority in validating identities. + +To achieve these operations, OpenPGP utilizes a set of [established cryptographic mechanisms](cyrptography_chapter). These building blocks are integrated into OpenPGP's format, which also manages and verifies identities. + + ## Who is the audience for this document?
