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.

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

public ASN1Sequence getRecipientEncryptedKeys()

toASN1Primitive

public ASN1Primitive toASN1Primitive()
Produce an object suitable for an ASN1OutputStream.
