Apdu may be illegel

Post by hinata » Wed Nov 16, 2016 1:50 pm

I play around with some Ecdsa codes when I got this error in debugshell command..

Code: Select all

>> /send 00D3020030350218345FBACE367196E4FEF900CA6CFB7B410621BABA1B28AF660219009DC2B6ECCB7CDE2855E88F6FD8D0B2349588AB503087C45E

Apdu may be illegel.Decoding conventions for command APDU should obey the rule in  7816-3  section 12.1.3


What does it mean, Apdu may be illegel.Decoding conventions for command APDU should obey the rule in 7816-3 section 12.1.3...?

But the code is still works, right? :')

Thank you in advance.
