success = false

jws = Chilkat::CkJws.new()

#  Load the JWS compact serialization.
jwsCompact = "eyJhbGciOiJIUzI1NiJ9.VGhpcyBpcyB0aGUgY29udGVudCB0byBzaWduLg.<signature>"
success = jws.LoadJws(jwsCompact)
if (success == false)
    print jws.lastErrorText() + "\n";
    exit
end

#  Copy the optional unprotected header of signature 0 into a JsonObject.  This applies to JWS in a
#  JSON serialization form that carries an unprotected header.
json = Chilkat::CkJsonObject.new()
success = jws.GetUnprotectedH(0,json)
if (success == false)
    print jws.lastErrorText() + "\n";
