Decodes the PKCS8ShroudedKeyBag given as ASN1Object.

Specified by:

decode in interface ASN1Type

Overrides:

decode in class KeyBag

Parameters:

obj - the PKCS8ShroudedKeyBag as ASN1Object

Throws:

CodingException - if the PKCS8ShroudedKeyBag cannot be decoded

toASN1Object

public ASN1Object toASN1Object()
                        throws CodingException

Returns this PKCS8ShroudedKeyBag as ASN1Object.

Specified by:

toASN1Object in interface ASN1Type

Overrides:

toASN1Object in class KeyBag

Returns:

this PKCS8ShroudedKeyBag as ASN1Object

Throws:

CodingException - if an de/encoding error occurs
