The values you have aren't secret. One is a random challenge. The other, assuming that what you gave us is the entire exchange, is probably an encrypted response to the challenge. The secret would be an additional 16 bytes of 3des key (or more than one 3des key, depending on the complexity of the secure messaging mechanism) Although the tlv in your sample command appears to match 7816-4 (i.e, tag 0x87 matches a padding indicator and ciphertext, 0x8E matches a cryptographic checksum) , the INS=86 apdu does not seem to be standardized, so I don't really know how it operates. _______________________________________________ opensc-devel mailing list [email protected] http://www.opensc-project.org/mailman/listinfo/opensc-devel
