Hi, I am getting an error when using this package on PACE-enabled passports. The following shows the error logs:

It works fine for BAC though

Can you test if it makes any difference changing aes key length to KEY_LENGTH.s256 in PACE.decryptNonce:583

Also word of advice, you're logging on the finest level which might leak sensitive data. Make sure to remove this data prior posting logs to public discourse.

ive tried hardcoding the blocksize in pointycastle to set the make params.iv.length the same as blockSize 

int get blockSize => 32;

but its weird because params.iv.length decreased from 32 to 16 after i did that

Parzivalxx commented 5 months ago

Hi I have seemed to fix the above error by changing some parts in the pointycastle package. It seems to work on Android well. However, when I try it on iOS, the app is stuck at "Ready to Scan", and doesnt actually scan the passport. Do you have any idea why that is?

smlu commented 5 months ago

Looking at your second log, I see that AES128 was selected. This happens here: https://github.com/ZeroPass/dmrtd/blob/8ced7600fb9fd84f0824bfaddc2fcc7bff655a7f/lib/src/proto/pace.dart#L547 Did you try changing the key size to 256 (KEY_LENGTH.s256)?

However, when I try it on iOS, the app is stuck at "Ready to Scan", and doesn't actually scan the passport. Do you have any idea why that is?

Do you get any specific log entry when app gets stuck? The ISO 14443 NFC interface for iOS was modified lately. It can be related to this: https://github.com/AndyQ/NFCPassportReader/issues/219 https://github.com/AndyQ/NFCPassportReader/issues/164#issuecomment-2139300643

Parzivalxx commented 5 months ago

Hi yes, i have tried changing it to KEY_LENGTH.s256 but the result is the same. I eventually decided to modify a part of the code in the pointycastle package here

I changed it to

final zeroIV = Uint8List(_cipher.blockSize);

and it now manages to work.

smlu commented 5 months ago

Looking at pointycastle code that you linked it's definitively wrong IV size for block cipher modes. There is already issue for this but no response yet: https://github.com/bcgit/pc-dart/issues/200

Parzivalxx commented 4 months ago

Thanks for the info, I have fixed the ios error, it had to do with permissions for the NFC to work: https://stackoverflow.com/questions/56453525/missing-required-entitlement-for-nfctagreadersession

smlu commented 4 months ago

Just to be clear, you had to add nfc entitlement to the iso project, is that right (like the example app)?

Parzivalxx commented 4 months ago

Yes, and I also had to add the following:

<key>NFCReaderUsageDescription</key>
        <string>App uses NFC to scan biometric pasports</string>
    <key>UIRequiredDeviceCapabilities</key>
    <array>
        <string>nfc</string>
    </array>
<key>com.apple.developer.nfc.readersession.iso7816.select-identifiers</key>
    <array>
        <string>A0000002471001</string>
        <string>A0000002472001</string>
        <string>00000000000000</string>
    </array>
smlu commented 4 months ago

Ah yes the A0000002471001 is AID for MRTD application. What are the other 2 for? Also can you confirm it does work on the latest iOS version?

mdxs commented 4 months ago

Just browsing what this lib might be able to do and what kind of issues are encountered, and the need to specify these AIDs sounded interesting to make it work... so I searched and found https://www.eftlab.com/knowledge-base/complete-list-of-application-identifiers-aid which seems to provide descriptions for two of the AID entries mentioned; the all zeroes wasn't on there as such. Not sure if it helps in this area, complete N00b here ;-)
