All applications on this page implement the OpenPGP standard. The authors of this webpage are not actively participating in the development of each of these third-party apps. No security audits have been done by us and, thus, we cannot provide any security guarantees.
If a project is missing and you would like it included, please open a pull request at github.com/OpenPGP/openpgp.org. Please note that we only include published, working software, which implements the standard. The software is ordered alphabetically within the sections.
