Method Detail

getInstance

public static KeyAgreeRecipientInfo getInstance(ASN1TaggedObject obj,
                                                boolean explicit)
Return a KeyAgreeRecipientInfo 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 KeyAgreeRecipientInfo getInstance(java.lang.Object obj)
Return a KeyAgreeRecipientInfo object from the given object.

Accepted inputs: null → null KeyAgreeRecipientInfo object ASN1Sequence input formats with KeyAgreeRecipientInfo structure inside

Parameters:
obj - the object we want converted.
Throws:
java.lang.IllegalArgumentException - if the object cannot be converted.

getVersion

public ASN1Integer getVersion()

getOriginator

public OriginatorIdentifierOrKey getOriginator()

getUserKeyingMaterial

public ASN1OctetString getUserKeyingMaterial()

getKeyEncryptionAlgorithm

public AlgorithmIdentifier getKeyEncryptionAlgorithm()

getRecipientEncryptedKeys

public ASN1Sequence getRecipientEncryptedKeys()

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.
