OpenPGP data is internally structured as "packets." We'll look at examples of this internal structure throughout the following chapters. Familiarizing ourselves with the internal format of OpenPGP data will enable us to debug issues. OpenPGP data is internally structured as "packets."

Gaining some familiarity with the internal structure of OpenPGP data will also help us to read the OpenPGP RFC, which describes the structure of OpenPGP packets in full detail.

In this text, however, most of the time we look at OpenPGP at a higher level of abstraction. (Most of the time, however, we will look at OpenPGP artifacts at a higher level of abstraction.)

## Interoperability ## Interoperability
OpenPGP was standardized in 1997 to encourage development of interoperable implementations. This has already been a success early on, but in recent years, there has been [much development of new implementations]((major_implementations)).

Historically, interoperability has only been tested ad-hoc. Since 2019 the Sequoia project is maintaining and operating the ["OpenPGP interoperability test suite"](https://tests.sequoia-pgp.org/), for more rigorous and systematic testing. The test suite has identified numerous [issues](https://gitlab.com/sequoia-pgp/openpgp-interoperability-test-suite#hall-of-fame).
