Topic: Changing key type


I'm working with DESFire EV1 cards that have their key type set to 3DES. I'd really like to change to 3 key 3DES or AES.  I have two questions I haven't been able to figure out.

1. Is it possible to change the key type on existing cards?
2. How do I set the key type for new cards?

Re: Changing key type

Maybe you could try libfreefare's mifare_desfire_change_key and mifare_desfire_set_default_key functions.

For further help you could try the manual pages for mifare_desfire and mifare_desfire_key

They are really good!
