getInstance
public static KeyAgreeRecipientInfo getInstance(org.bouncycastle.asn1.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.
