EP11: Support tolerated new crypto cards
|
|
|
299615 |
|
|
|
299615 |
With just toleration support of new crypt cards, new crypto
|
|
|
299615 |
cards are reported as the last known crypto card version.
|
|
|
299615 |
E.g. a CEX7 card is reported as CEX6, when CEX6 is the last
|
|
|
299615 |
known crypto card version.
|
|
|
299615 |
|
|
|
299615 |
The EP11 token checks the card versions and needs to distinguish
|
|
|
299615 |
tolerated cards from supported cards. New (tolerated) crypto cards
|
|
|
299615 |
may have different API and firmware versions, and thus need to be
|
|
|
299615 |
handled differently.
