// overview
What it does
PGP sign is one of 55 tools in Hexkit, a desktop developer toolbox that runs entirely on your own machine. Produce a detached, text-normalized OpenPGP signature over a message.
Because Hexkit is a native app rather than a web page, anything you paste into the pgp sign stays local — there are no uploads, no accounts and no telemetry. You can handle keys, signatures and encrypted messages even with the network turned off, which makes it safe for tokens, keys and production data.

How to use PGP sign
- 1
Open Hexkit and select "PGP sign", or press the command-palette key and start typing its name.
- 2
Paste your keys and message. Produce a detached, text-normalized OpenPGP signature over a message.
- 3
Read or copy the result. Everything is computed locally by Hexkit's Rust core, so nothing is ever uploaded.
Tip: the command palette opens any tool in one keystroke.
