How to build

1. Install Go 1.20 or higher
2. Install templ go install github.com/a-h/templ/cmd/templ@latest
3. Run templ generate in project root directory template go files.

How to run

1. Run server from server/pass-it.go file.
2. To simulate mobile client, run tools/crypto.go.
3. It first generates key pair and prints encoded public key to be used as key parameter in Store request.
4. Then it waits for browser session id sent by server in Fetch stream initial event to be entered by user in console.
5. Then it generates signature for Confirm request.
6. Open http://localhost:8080 to receive secret.

Known issues:

• Sending confirmation with wrong signature will purge the key from cache and client cannot retry operation
