How to parse

byte[] bytes = HexUtil.parseHex("50045649534157131000023100000033D44122011003400000481F");

BerTlvParser parser = new BerTlvParser(LOG);
BerTlvs tlvs = parser.parse(bytes, 0, bytes.length);
  
BerTlvLogger.log("    ", tlvs, LOG);

How to build

byte[] bytes =  new BerTlvBuilder()
                .addHex(new BerTag(0x50), "56495341")
                .addHex(new BerTag(0x57), "1000023100000033D44122011003400000481F")
