This repo contains custom build GPG node for n8n. It includes the node linter and other dependencies. This node was build with same functionality of the already build PGP node by Bram. However to fix the openPGP bug this node has allowInsecureDecryptionWithSigningKeys configed. Due to security issues that may be caused by this work around I recommend you first try to use this node here.
