org.bouncycastle.asn1 (Bouncy Castle Library 1.52 API Specification)

# Package org.bouncycastle.asn1

A library for parsing and writing ASN.1 objects.

See: Description

- Interface Summary
  Interface | Description
  --- | ---
  ASN1ApplicationSpecificParser | Interface to parse ASN.1 application specific objects.
  ASN1Choice | Marker interface for CHOICE objects - if you implement this in a role your own object any attempt to tag the object implicitly will convert the tag to an explicit one as the encoding rules require.
  ASN1Encodable | Basic interface to produce serialisers for ASN.1 encodings.
  ASN1Encoding | Supported encoding formats.
  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 |
  ASN1TaggedObjectParser |
  BERTags |
  DERTags | Deprecated use BERTags
  InMemoryRepresentable | Interface implemented by objects that can be converted from streaming to in-memory objects.

- Class Summary
  Class | Description
  --- | ---
  ASN1Boolean | Public facade of ASN.1 Boolean data.
  ASN1EncodableVector | Mutable class for building ASN.1 constructed objects.
  ASN1Enumerated | Class representing the ASN.1 ENUMERATED type.
  ASN1GeneralizedTime | Base class representing the ASN.1 GeneralizedTime type.
  ASN1Generator |
  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.
  ASN1Object | Base class for defining an ASN.1 object.
  ASN1ObjectIdentifier | Class representing the ASN.1 OBJECT IDENTIFIER type.
  ASN1OctetString | Abstract base for the ASN.1 OCTET STRING data type This supports BER, and DER forms of the data.
  ASN1OutputStream | Stream that produces output based on the default encoding for the passed in objects.
  ASN1Primitive | Base class for ASN.1 primitive objects.
  ASN1Sequence | ASN.1 `SEQUENCE` and `SEQUENCE OF` constructs.
  ASN1Set | ASN.1 `SET` and `SET OF` constructs.
  ASN1StreamParser | A parser for ASN.1 streams which also returns, where possible, parsers for the objects it encounters.
  ASN1TaggedObject | ASN.1 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).
  ASN1UTCTime | - * UTC time object.
  BERApplicationSpecific |
  BERApplicationSpecificParser |
  BERConstructedOctetString | Deprecated use BEROctetString
  BERGenerator |
  BEROctetString |
  BEROctetStringGenerator |
  BEROctetStringParser |
  BEROutputStream |
  BERSequence |
  BERSequenceGenerator |
  BERSequenceParser |
  BERSet |
  BERSetParser |
  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).
  BERTaggedObjectParser |
  DERApplicationSpecific | Base class for an application specific object
  DERBitString |
  DERBMPString | DER BMPString object.
  DERBoolean | Deprecated use ASN1Boolean
  DEREncodableVector | a general class for building up a vector of DER encodable objects - this will eventually be superceded by ASN1EncodableVector so you should use that class in preference.
  DEREnumerated | Deprecated Use ASN1Enumerated instead of this.
  DERExternal | Class representing the DER-type External
  DERExternalParser |
  DERGeneralizedTime | DER Generalized time object.
  DERGeneralString |
  DERGenerator |
  DERIA5String | DER IA5String object - this is an ascii string.
  DERInteger | Deprecated Use ASN1Integer instead of this,
  DERNull | A NULL object.
  DERNumericString | DER NumericString object - this is an ascii string of characters {0,1,2,3,4,5,6,7,8,9, }.
  DERObjectIdentifier | Deprecated Use ASN1ObjectIdentifier instead of this,
  DEROctetString |
  DEROctetStringParser |
  DEROutputStream | Stream that outputs encoding based on distinguished encoding rules.
  DERPrintableString | DER PrintableString object.
  DERSequence |
  DERSequenceGenerator |
  DERSequenceParser |
  DERSet | A DER encoded set object
  DERSetParser |
  DERT61String | DER T61String (also the teletex string), try not to use this if you don't need to.
  DERT61UTF8String | DER T61String (also the teletex string) - a "modern" encapsulation that uses UTF-8.
  DERTaggedObject | DER 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).
  DERUniversalString | DER UniversalString object.
  DERUTCTime | DER UTC time object.
  DERUTF8String | DER UTF8String object.
  DERVisibleString | DER VisibleString object encoding ISO 646 (ASCII) character code points 32 to 126.
  DLOutputStream | Stream that outputs encoding based on definite length.
  DLSequence | The DLSequence encodes a SEQUENCE using definite length form.
  DLSet | The DLSet encodes ASN.1 SET value without element ordering, and always using definite length form.
  DLTaggedObject | Definite Length 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).
  OIDTokenizer | class for breaking up an OID into it's component tokens, ala java.util.StringTokenizer.
