Integer Parser
Listing 3 illustrates the parsing code for an integer type.
Listing 3 Integer Parser
case INT_CLASS:
for (i = *offset + 2; i <= *offset + elementLength + 1; i++)
printf("%x", dataSet[i]);
printf("\n");
*offset += 4;
parseAsnElement(dataSet, offset, elementLength, overallLength);
break;
The first four lines of Listing 3 extract the integer data from the ASN.1 encoding. Next, I move the offset along past the integer element and this is then followed by a recursive call to a containing method called parseAsnElement(). We’ll see the overall picture in a few moments!
