public Class BEROctetString

extends ASN1OctetString
Class Inheritance
Imports
java.io.IOException
ASN.1 OctetStrings, with indefinite length rules, and constructed form support.

The Basic Encoding Rules (BER) format allows encoding using so called "constructed form", which DER and CER formats forbid allowing only "primitive form".

This class always produces the constructed form with underlying segments in an indefinite length array. If the input wasn't the same, then this output is not faithful reproduction.

See ASN1OctetString for X.690 encoding rules of OCTET-STRING objects.
