+1 on this, would really like to see this as a feature.
Using this without reading is frustrating :<
I also want this feature. I have the possibility to use a card printer/writer. And this way would make it very easy for me to get the B keys as I just can write/print to an gen1a magic card.
Maybe this issue should be on the apps repo and not firmware as nfc magic is an standalone app there?
Latest version NfcMagic support gen1/gen2 writing.
@skotopes I'm sorry, but the issue was about the backdoor read, which is still now implemented.
I agree that it would be better to have it in good faps repo.
Would it be good if I will reopen it there as a feature proposal?
@mishamyte I've reopened and moved it to appropriate repository.
Description of the feature you're suggesting.
Overview:
Right now NFC Magic app supports next functionality for magic tags:
It would be nice to add also support of read backdoor command. For that case flow of reading could be simplified. Instead of trying to authenticate with user dictionary + standard dictionary, tag could be read fully with a backdoor command.
Usage steps:
Tech details for read commands:
40(7)
,43
,30xx
+ crc40(7)
,30xx
+ crc (need validate should crc be present here)Potential problems: Now detection of Gen 1 tags is done, using
40(7)
command and concrete type (Gen1A/Gen1B) is not detected. For read it could be done via iteration through the read sequence for Gen1A, if didn't worked - for Gen1B. Which could ruin UX from the PoV of waiting time.Implementation in existing products: It is implemented at least in next solutions:
cview
commandAnything else?
