# SOP-Java-Picocli [](https://javadoc.io/doc/org.pgpainless/sop-java-picocli) [](https://search.maven.org/artifact/org.pgpainless/sop-java-picocli) Implementation of the [Stateless OpenPGP Command Line Interface](https://datatracker.ietf.org/doc/draft-dkg-openpgp-stateless-cli/) specification. This terminal application allows generation of OpenPGP keys, extraction of public key certificates, armoring and de-armoring of data, as well as - of course - encryption/decryption of messages and creation/verification of signatures. ## Install a SOP backend This module comes without a SOP backend, so in order to function you need to extend it with an implementation of the interfaces defined in `sop-java`. An implementation using PGPainless can be found in the module `pgpainless-sop`, but it is of course possible to provide your own implementation. Just install your SOP backend by calling ```java // static method call prior to execution of the main method SopCLI.setSopInstance(yourSopImpl); ``` ## Usage To get an overview of available commands of the application, execute ```shell java -jar sop-java-picocli-XXX.jar help ``` If you just want to get started encrypting messages, see the module `pgpainless-cli` which initializes `sop-java-picocli` with `pgpainless-sop`, so you can get started right away without the need to manually wire stuff up. Enjoy!
