Constructor Detail

DERExternal

public DERExternal(ASN1EncodableVector vector)

Construct a DER EXTERNAL object, the input encoding vector must have exactly two elements on it.

Acceptable input formats are:

• ASN1ObjectIdentifier + data DERTaggedObject (direct reference form)
• ASN1Integer + data DERTaggedObject (indirect reference form)
• Anything but DERTaggedObject + data DERTaggedObject (data value form)

Throws:

java.lang.IllegalArgumentException - if input size is wrong, or

DERExternal

public DERExternal(ASN1ObjectIdentifier directReference,
                   ASN1Integer indirectReference,
                   ASN1Primitive dataValueDescriptor,
                   DERTaggedObject externalData)

Creates a new instance of DERExternal See X.690 for more informations about the meaning of these parameters

Parameters:

directReference - The direct reference or null if not set.

indirectReference - The indirect reference or null if not set.

dataValueDescriptor - The data value descriptor or null if not set.

externalData - The external data in its encoded form.
