Package org.bouncycastle.asn1

A library for parsing and writing ASN.1 objects. Support is provided for DER and BER encoding.

Interface Summary

Interface	Description
ASN1BitStringParser	A basic parser for a BIT STRING object

ASN1Encodable	Basic interface to produce serialisers for ASN.1 encodings.
ASN1Encoding	Supported encoding formats.
ASN1ExternalParser	Parser DER EXTERNAL tagged objects.
ASN1OctetStringParser	A basic parser for an OCTET STRING object
ASN1SequenceParser	A basic parser for a SEQUENCE object
ASN1SetParser	A basic parser for a SET object
ASN1String	General interface implemented by ASN.1 STRING objects for extracting the content String.
ASN1TaggedObjectParser	Interface for the parsing of a generic tagged ASN.1 object.
BERTags
InMemoryRepresentable	Interface implemented by objects that can be converted from streaming to in-memory objects.

ASN1InputStream	A general purpose ASN.1 decoder - note: this class differs from the others in that it returns null after it has read the last object in the stream.
ASN1Integer	Class representing the ASN.1 INTEGER type.
ASN1Null	A NULL object - use DERNull.INSTANCE for populating structures.

BERBitString
BERBitStringParser	Deprecated. Check for 'ASN1BitStringParser' instead

BERSetParser	Deprecated. Check for 'ASN1SetParser' instead
BERTaggedObject	BER TaggedObject - in ASN.1 notation this is any object preceded by a [n] where n is some number - these are assumed to follow the construction rules (as with sequences).
DERBitString	A BIT STRING with DER encoding - the first byte contains the count of padding bits included in the byte array's last byte.
