Method Detail

getInstance

public static KeyAgreeRecipientIdentifier getInstance(ASN1TaggedObject obj,
                                                      boolean explicit)

Return an KeyAgreeRecipientIdentifier object from a tagged object.

Parameters:

obj - the tagged object holding the object we want.

explicit - true if the object is meant to be explicitly tagged false otherwise.

Throws:

java.lang.IllegalArgumentException - if the object held by the tagged object cannot be converted.

getInstance

public static KeyAgreeRecipientIdentifier getInstance(java.lang.Object obj)

Return an KeyAgreeRecipientIdentifier object from the given object.

Accepted inputs:

• KeyAgreeRecipientIdentifier object
• ASN1Sequence input formats with IssuerAndSerialNumber structure inside
• ASN1TaggedObject with tag value 0: a KeyAgreeRecipientIdentifier data structure

Note: no byte[] input!

Parameters:

obj - the object we want converted.

Throws:

java.lang.IllegalArgumentException - if the object cannot be converted.

getIssuerAndSerialNumber

public IssuerAndSerialNumber getIssuerAndSerialNumber()

getRKeyID

public RecipientKeyIdentifier getRKeyID()

toASN1Primitive

public ASN1Primitive toASN1Primitive()

Produce an object suitable for an ASN1OutputStream.

Specified by:

toASN1Primitive in interface ASN1Encodable

Specified by:

toASN1Primitive in class ASN1Object

Returns:

a primitive representation of this object.
