ber-parser

A simple ASN1 BER parser

purpose

This module implements parsing of data encoded according to ASN1 Basic Encoding Rules (BER) of ITU-T X.690 Recommendations.

usage

All the processing is done within one function: readTlv(buffer: Buffer, pos: number, parseValues?: boolean)
- buffer - actual data to parse
- pos - start position in the buffer
- parseValue - indicates whether the individual type-dependant parsers should be applied to values (they are declared in a CLASS_TYPES object for some common types)

You can print out to console the contents of the resulting object with an additional function showTlv(tlv).
