The tools I work with, grouped by what they do.
In use in my current role
Work you can open right now.
An online table for Cuarenta, Quito's traditional card game, with four remote players plus read-only spectators.
The server is the single authority: it deals, validates every play, and sends each player only what they are allowed to see.
An open JavaScript reference implementation from 2016 for signing electronic invoices with XAdES-BES for Ecuador’s tax authority (SRI).
It assembles the invoice XML, computes the 49-digit access key with its mod-11 check digit, extracts the key pair from a PKCS#12 certificate, and signs the document as XMLDSig.
