Instructions:
1.: insert the received public key
2.: insert the JWT/JWS token in Base64Url encoding
3.: press the "Import key" button
4.: if the public key is valid the "Verify" button is enabled
5.: press the "Verify button"
6.: receive the verification status
7.: to see the decoded header, payload or expiration data press the named buttons
