Reading Length in ASN.1

private int readLength(DataInputStream inputStream)

byte[] bytes = readBytes(inputStream, 1);

BitIterator iterator = new BitIterator(bytes);

String mostSignificant = iterator.getBits(1);

String value = iterator.getBits(7);

int length = Integer.parseInt(value, 2);

if (!mostSignificant.equals("0"))

{

bytes = readBytes(inputStream, length);

value = byteArraytoHex(bytes);

length = Integer.parseInt(value, 16);

}

System.out.println("Length of the record " + length);

return length;
