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.

It is a system based on well-understood [cryptographic building blocks](cyrptography_chapter). OpenPGP supports the secure delivery of files and messages between a sender and a recipient.

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](component_signatures_chapter) about keys and identities, similar to the role of a Certificate Authority in validating identities. - -To enable these operations, OpenPGP utilizes a set of [established cryptographic mechanisms](cyrptography_chapter). These building blocks are integrated into OpenPGP's standard, which also addresses identities and their verification. +- [Issue and validate certifications](component_signatures_chapter) about keys and identities, similar to the role of a Certificate Authority in validating identities. ## Who is the audience for this document?
