public class Asn1CerOutputStream
This class implements the output stream to encode ASN.1 messages as specified in the Canonical Encoding Rules (CER) as specified in the ITU-T X.690 standard. A reference to an object of this type is passed to each of the ASN.1 type encode methods involved in encoding a particular message type.
