But "another 3 bytes" is needed only for tcos, it always only 3 bytes need for all tcos key types(sizes). If I use RSA_NO_PADDING, which format for input buffer for encryption needed? _______________________________________________ opensc-devel mailing list opensc-devel@lists.opensc-project.org http://www.opensc-project.org/mailman/listinfo/opensc-devel
