How it works
- 01
Paste the signed document: a JWT from El Salvador, or the XML from Costa Rica, the Dominican Republic, Guatemala or Panama.
- 02
If it is a JWT, add the issuer's certificate (the MH .crt, or a .pem or .cer). XML signatures usually carry the certificate inside the signature itself.
- 03
Verification runs with the Web Crypto API in your browser: neither the document nor the certificate is sent to any server.
