Hi giokoguashvili,
the function berTlvFirstByte() in Tag class has throw exception when i read DG 7 or DG11 or DG12, it execute Bytes() of SecureMessagingPipe step
it nothing happen and read data success in DG1 and DG2
what im missing?

new DO87(_kSenc).FromCommandApdu(_commandApdo).Encrypted()

This is a gem, very hard to find MRTD on .NET.

So I am giving this a try with DemoApp, I have updated the MRZ data correctly and Card ATR is fetching and starts reading past EF.COM;
0 - 5
..
..
13110 - 230
13340 - 0

Till it reaches 13340 - 0
and throws Sequence contains no elements exception at line 22 of ExtractedDO99.cs

for line
return parsetBerTLV.Data.Where(tlv => tlv.T == "99").First().Bytes();

Any idea what might be the issue ? I can use the same MRZ info successfully with same reader under PCSC dumpmrtd.js script so I know passport and reader is ok as well as MRZ data; dob, expiry, docNo.

Like the example on main page, I tried to read an italian identity card with only one row of code:

Dim dg = Await New SmartCardContent(New MRZInfo("CA06903XA", New Date(1986, 2, 3), New Date(2028, 2, 3))).Content

and it works very fine !!
But, first of this I'd like to test if there is a card reader connected and to test if there is a card into the reader because in these cases the command don't break and wait wait wait.
How can I test the presence of the reader and the card ?
Is there any documentation about this DLL ??
Many many thanks
Sergio

Whatever I try I can't do a simple "Internal Authentication" with 8 byte challange. Maybe this is not an issue about this library but is there any sample code about this? Thanks

Hi,

when I place the card to the reader, there is a system exception about "System.Exception: Error: The smart card has been reset, so any shared state information is invalid."
