Public Methods

public static KeyAgreeRecipientInfo getInstance (ASN1TaggedObject obj, boolean explicit)

return a KeyAgreeRecipientInfo object from a tagged object.

Parameters

return a KeyAgreeRecipientInfo object from the given object.

Parameters
obj the object we want converted.
Throws
IllegalArgumentException if the object cannot be converted.
