Package org.bouncycastle.openpgp.api Description

The

api

package contains a high-level OpenPGP API layer on top of the

openpgp

mid-level API. It is tailored to provide a modern OpenPGP experience, following the guidance from rfc9580 ("OpenPGP v6"), while also being interoperable with rfc4880 ("OpenPGP v4").

From an architectural point of view, the hierarchy of the individual layers is as follows:

• api

  specifies a high-level API using mid-level implementations from

  openpgp

  . This layer strives to be easy to use, hard to misuse and secure by default.

• openpgp

  defines a powerful, flexible, but quite verbose API using packet definitions from

  bcpg

  .

• bcpg

  implements serialization / deserialization of OpenPGP packets. It does not contain any business logic.
