Dear Jim, Can you help on the last UMIKey tool for the user? * When the user clicks on the button of 'Change UmiKey Options Above', UmiKey firmware will check the password, if correct, will change the user-specified settings. Attached screen snapshot is as attached. Thanks a lot

Jim, Some suggestions about the UMIKEY Write CA 0.2: 1. If password is not matched. Do not erase Security data. There are two reasons. First,if user mis-types in error password. He/She will damage his/her key immediately! Second, if someone wants to damage my key. He/She just needs to type in a error password to destroy my key! Suggestion: If the password is incorrect. Stop Writing anything into key but a error counter. Error counter is stored in EEPROM. If the error number overflows, then wipe out all data on the Umikey. By default the error counter max should be 5. So a hacker can't try indefinitely. 2. The count resets to 0 when the password matches correctly. Thanks
