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

return a KeyAgreeRecipientInfo object from the given object.

Parameters:

obj - the object we want converted.

Throws:

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

getVersion

public DERInteger getVersion()

getUserKeyingMaterial

public ASN1OctetString getUserKeyingMaterial()

getKeyEncryptionAlgorithm

public AlgorithmIdentifier getKeyEncryptionAlgorithm()

getRecipientEncryptedKeys

public ASN1Sequence getRecipientEncryptedKeys()

toASN1Object

public DERObject toASN1Object()

Produce an object suitable for an ASN1OutputStream.
