Description
Context
When setting ValueFileType's communication mode to encrypt
, the command hf mfdes value --op clear -m encrypt [... other crypto flags]
, the execution returns the following result:
[!] Wrong communication mode. Check settings. command: f5
[=] Key num: 0 Key algo: aes Key[16]: [AES Key]
[=] Secure channel: ev1 Command set: niso Communication mode: encrypt
[=] Session key [16]: [Session Key]
[=] IV [16]: [IV]
[!] CRC32 error.
[!!] Desfire GetFileSettings command returns wrong data
When changing the file communication mode outside of encrypt
, the command works as intended. I've used DesFire EV1 for the test. Cannot confirm if EV2/EV3 will have this issues.
Commands to Replicate The Issue
Here's all the command that's been executed leading up to the error.
