Detailed Description

Convert ASN.1 data to (meaningful) strings.

This purely static class provides decoder functions to convert ASN.1 data into human readable strings.

The class supports a handfull build-in decoder functions:
prRaw(), prHex(), prInt(), prAscii(), prBcd() and prTbcd().

RegAsn1CdrPrint().
