Making Repl Identity More Accessible


Matt Iselin

In August last year, we announced Repl Identity, a signed identity for every Repl that your code can use to authenticate other Repls when communicating with your APIs and services.

For a quick refresher, you can try out the demo that decodes the identity token and outputs it to the shell.

We have a Go package for this already (docs here), but there's a limited selection of bindings for other languages. To that end, we're rolling out a command-line tool in every Repl that allows you to use features like Repl Identity in any language that can run a subprocess.

Here's a quick demo that you can try in our own Repls:

$ TOKEN=$($REPLIT_CLI identity create -audience="the target repl id")
$ $REPLIT_CLI identity verify -audience="the target repl id" -token="${TOKEN}" -json
  "replid": "ff2d906a-0a47-482b-9067-1ac0a078c394",
  "user": "mattiselin",
  "slug": "replit-cli",
  "aud": "the target repl id"

Check out this example Python Repl that creates and verifies a Repl Identity token:

You can wrap this command in your code to do token creation and verification without needing a direct language binding.
