Plugin Signing

Edit pageLast modified: 09 April 2024

Plugin Signing is a mechanism introduced in the 2021.2 release cycle to increase security in JetBrains Marketplace and all of our IntelliJ-based IDEs.

The Marketplace signing is designed to ensure that plugins are not modified over the course of the publishing and delivery pipeline. If the author does not sign the plugin or has a revoked certificate, a warning dialog will appear in the IDE during installation.

On our side, we will check if the public part of a key is present, and we will verify the signature. This is similar to the Google upload key mechanism.
