VhlCfg / File / DesfireFormatAppKeySettings Value
This configuration value was deprecated and removed in firmware 2.12.00. It is unsupported in this and all later versions.
This entry is only needed for running VHLFormat() and contains the necessary key settings parameter (KS1/2/3) for defining an application. KS3 is only needed by EV2 cards and has to be omitted for compatibility reasons if not needed.
Rules for coding key settings:
- if KS1 is different from the existing one, the key settings will be changed.
- if KS2 is different from the existing one the existing application will be deleted and created again.
- if KS3 is different from the existing one the existing application will be deleted and created again.
Properties
- Value ID: 0x0300/0x44
- Default value: AllowChangeAppMasterKey|AllowDirectoryList|AllowCreateDeleteFile|ConfigurationChangeable|0x10 AES|0x0D
Format
