# Ecosystem PGPainless consists of an ecosystem of different libraries and projects. ## [PGPainless](https://github.com/pgpainless/pgpainless) The main repository contains the following components: * `pgpainless-core` - core implementation - powerful, yet easy to use OpenPGP API * `pgpainless-sop` - super simple OpenPGP implementation. Drop-in for `sop-java` * `pgpainless-cli` - SOP CLI implementation using PGPainless ## [SOP-Java](https://github.com/pgpainless/sop-java) An API definition and CLI implementation of the [Stateless OpenPGP Protocol](https://www.ietf.org/archive/id/draft-dkg-openpgp-stateless-cli-03.html). * `sop-java` - generic OpenPGP API definition * `sop-java-picocli` - Abstract CLI implementation for `sop-java` ## [WKD-Java](https://github.com/pgpainless/wkd-java) Implementation of the [Web Key Directory](https://www.ietf.org/archive/id/draft-koch-openpgp-webkey-service-13.html). * `wkd-java` - abstract WKD discovery implementation * `wkd-java-cli` - CLI application implementing WKD discovery using PGPainless * `wkd-test-suite` - Generator for test vectors for testing WKD implementations ## [VKS-Java](https://github.com/pgpainless/vks-java) Client-side API for communicating with Verifying Key Servers, such as https://keys.openpgp.org/. * `vks-java` - VKS client implementation ## [Cert-D-Java](https://github.com/pgpainless/cert-d-java) Implementations of the [Shared OpenPGP Certificate Directory specification](https://sequoia-pgp.gitlab.io/pgp-cert-d/). * `pgp-certificate-store` - abstract definitions of OpenPGP certificate stores * `pgp-cert-d-java` - implementation of `pgp-certificate-store` following the PGP-CERT-D spec. * `pgp-cert-d-java-jdbc-sqlite-lookup` - subkey lookup using sqlite database ## [Cert-D-PGPainless](https://github.com/pgpainless/cert-d-pgpainless) Implementation of the [Shared OpenPGP Certificate Directory specification](https://sequoia-pgp.gitlab.io/pgp-cert-d/) using PGPainless. * `pgpainless-cert-d` - PGPainless-based implementation of `pgp-cert-d-java`. * `pgpainless-cert-d-cli` - CLI frontend for `pgpainless-cert-d`.
