Abstract
A method, system, and computer program are disclosed to transport an encrypted key across multiple, diverse systems which provides the relevant and necessary information to guarantee a successful decryption of the key. The method prepares an ASN.1 encoding file at the sender which contains the key. The receiver performs the method to decode the ASN.1 encoded file. In this manner, only the data and the contents of the portable key need to be sent to guarantee successful decryption at the receiver.
