All Implemented Interfaces:

Direct Known Subclasses:

CertificateBag, CRLBag, KeyBag, SafeContentsBag, SecretBag

public abstract class SafeBag

extends Attributes

implements ASN1Type

This class implements the PKCS#12 structure SafeBag.

The PKCS#12 Personal Information Exchange Syntax Standard defines the SafeBag structure as collection of one particular piece of information (a key, a certificate, ...) and some additional attributes for forming the basic building block of a PFX PDU:

 SafeBag :== SEQUENCE {
  bagType         OBJECT IDENTIFIER,
  bagContent      [0] EXPLICIT ANY DEFINED BY bagType,
  bagAttributes   Attributes OPTIONAL   -- from X.501
 }

Constructor Detail

SafeBag

protected SafeBag()

Default Constructor. Creates an empty SafeBag object. Implements the ASN1Type interface.

SafeBag

protected SafeBag(String friendlyName,
                  byte[] localKeyID)

Creates a new SafeBag from a friendly name and a local key ID.

Method Detail

create

public static SafeBag create(ObjectID oid)
                      throws PKCSException

Creates a new SafeBag from a given ObjectID.

Parameters:

oid - the object id of the bag to create

Returns:

the just created SafeBag

Throws:

PKCSException - if there is no bag type registered for the given object id

register

public static void register(ObjectID oid,
                            Class cls)

Registers a new implementation for a PKCS#12 SafeBag defined through the given ObjectID.

Parameters:

oid - the object id of the PKCS#12 SafeBag to be registered

cls - the implementing class

encodeSafeContents

protected static byte[] encodeSafeContents(SafeBag[] safeBags)
                                    throws CodingException

Creates the SafeContants byte array as needed by AuthenticatedSafe from an array of SafeBags.

Parameters:

safeBags - the SafeBags to encode

Returns:

the SafeBags as DER encoded Sequence of SafeBag

encodeSafeContentsAsASN1Object

protected static ASN1Object encodeSafeContentsAsASN1Object(SafeBag[] safeBags)
                                                    throws CodingException

Creates the SafeContants ASN1Object as needed by SafeContentsBag from an array of SafeBags.

Parameters:

safeBags - the SafeBags to encode

Returns:

the SafeBags as ASN1Object of SafeBag

parseSafeContents

protected static SafeBag[] parseSafeContents(byte[] safeContents)
                                      throws CodingException

Parses the SafeContents data structure and returns the included SafeBags.

Parameters:

safeContents - the SafeContents ASN.1 structure as byte array

Returns:

the SafeBags within this SafeContents

Parameters:

safeContents - the SafeContents ASN.1 structure as ASN1Object

Returns:

the SafeBags within this SafeContents

Throws:

CodingException - if an error occurs during parsing the safe contents
