Examples of codec.asn1.DEREncoder

codec.asn1.DEREncoder
If ,right after instantiating the encoder, the strict parameter is set to true, the encoder uses the strict encoding rules from X680/X690 for Sets and SetOfs. As long as the flag is not set, the encoder behaves as usual. @author Volker Roth @author Stefan Endler @version "$Id: DEREncoder.java,v 1.7 2007/09/12 13:58:14 sendler Exp $"
