Hi,

Im tryng to change the key of picc level for DES to AES but I cant the card alwasy response me with 0x1E. Can you give me more information about the secuencial steps to follow in this case.

writing my log below.

Forgive but I have been wrong with some dates, so I rewrite a new log:

Current DES key: 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00.

New AES key: 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00.

Session key: 0x00, 0x00, 0x00, 0x00, 0x74, 0x92, 0xaf, 0xb0.

CRC16 :0x1B, 0x5B.
the CRC16 is calculated over: 0xC4, 0x80, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x01.

finally (before encrypted to send): 0xC4, 0x80, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x01, 0x1B, 0x5B, 0x00, 0x00, 0x00, 0x00, 0x00.

finally (encrypted to send): 0xC4, 0x80, 0x39, 0x2A, 0xE1, 0xF2, 0x27, 0xB9, 0xD8, 0xA8, 0x58, 0x24, 0x79, 0x63, 0x49, 0x66, 0xB4, 0x1B, 0x1B, 0x1F, 0x1E, 0x64, 0xEB, 0x8F, 0x7F, 0xB6.

thanks and regards.
