Hi

I'm trying to install an Applet which I made in SIM card by pyApdutool.
But it is blocked with "Download Cap error: Check Card Cryptogram failed".

It seems that I have to enter the right keys (S-ENC, C-MAC, DEK) for GP Verify.
How can I know those Keys(S-ENC, C-MAC, DEK)?
Is it depend on SIM card manufacture?
Then, only SIM card manufacture know them?

Please let me know about that keys.
Thanks
