epass2003 RSA/2048 Failed to Generate Key on OSX, VirtualBOX #301

rvalle · 2014-10-16T11:48:10Z

Hi!
I am having trouble generating RSA 2048 keys on epass2003.
I get:

./pkcs15-init --auth-id 1 --generate-key rsa/2048 --key-usage sign,decrypt --label "MyRSAKey"
Using reader with a card: Feitian ePass2003 00 00
Failed to generate key: Transmit failed

The problem does not seem to happen when generating an RSA/1024 key

I am testing by building the tag: 0.14.0 and the HEAD
I have tried to include also configure with --enable-sm

Any idea what could be about?

A opensc debug trace would help.

This suggests that you must us the --pin option.

Ok,

To make things easier I downloaded and built the latest versions of the following modules:

OpenSC 0.14.0
ccid-1.4.18
pcsc-lite-1.8.12

you can find the trace here:

So this may be a timing problem, that is covered up by Virtual Box on my system.

Looking closer, I don't see where you verified the PIN.

What is the command line you used?

What is the profile you are using?

Is your card out of memory?

@rvalle, generate a pcscd log as described in http://pcsclite.alioth.debian.org/ccid.html#support

rvalle · 2014-10-19T18:57:28Z

pcsc timeout sounds like possible cause to me.

I can consistently generate 1024 bit keys, and 2048 consistently fail.

for the same reason I don't think the PIN should be the problem.

I am runing on a macbookpro OSX/debian 7 under virtual box.

Will try capturing those logs.
R.

rvalle · 2014-10-19T19:25:03Z

Actually, the communication with the token is far from great.

many times pkcs15-tool reports token not found, and I have to re-insert several times until it is finally detected (I dont know up to which point this is normal / the software is stable).

here you can find the requested logs:

http://pastebin.com/wGTdX4GF

the command used for generating the key and its output is:

 pkcs15-init --auth-id 1 --generate-key rsa/2048 --use-default-transport-key --key-usage sign,decrypt --label "TestRootKey"
Using reader with a card: Feitian ePass2003 00 00
Failed to generate key: Transmit failed

thanks!
R.

LudovicRousseau · 2014-10-20T15:06:52Z

The command at line 804 is taking around 10 seconds and you can see the time requests sent by the reader:

01102953 <- 000000 80 00 00 00 00 00 43 80 03 00
00000042 commands.c:1519:CCID_Receive() Time extension requested: 0x03
00000010 commands.c:1525:CCID_Receive() New timeout: 9000 ms

Then the next APDU is sent and the reader do not replay before the driver timout of 3000 ms. So we get a:

03061708 ccid_usb.c:798:ReadUSB() read failed (2/6): -7 Invalid argument

-7 is LIBUSB_ERROR_TIMEOUT

After looking in the CCID driver I note that the timout of 3000 ms is the default timeout and is not calculated from the card ATR. The calculated timeout would be 94930 ms so much more than 3000 ms.

Can you edit the file ccid/src/defs.h and change the definition of DEFAULT_COM_READ_TIMEOUT to something like 100_1000 instead of 3_1000?
Then rebuild and reinstall the CCID driver. And redo your test.

rvalle · 2014-10-20T20:31:23Z

I did the test, and it is still failing.
It takes much longer to fail. May be there is some kind of deadlock.

Its actually very hard to get the system to a point in which the token is recognized.

I randomly restart pcscd, and insert/remove the token till I can get its serial via opensc-tool and then, only sometimes will accept to try generating the key.

I get a lot of card not present, or empty slot, binding failed, unsupported card etc.

I test my setup with an older token (ePass PKI) and it looks more robust, but still with lots of similar problems.

I wonder if I have something too old in my environment. I have lib-usb-1.0-0_1.0.11, on Debian 3.2.60-1+deb7u3.

I might just replicate your environment and test. Which ubuntu is it? any particular version?

LudovicRousseau · 2014-10-21T07:45:40Z

I moved the Feitian ePass2003 token from the "supported" to the "should work" list. http://pcsclite.alioth.debian.org/ccid/shouldwork.html#0x096E0x0807

Maybe I have a ePass2003 and will be able to make tests myself and then maybe move the token in the "unsupported" list.

I don't think you have a software problem with libusb or another component. Maybe you have a USB hardware problem. Test on another computer. Or maybe your token is broken.

This could also be hardware. Defective token, dirty or bent USB plug or port. Power to USB not left on?

No problem generating 2048 key on an old PC "Ubuntu 12.04.4 LTS" native 32bits
it takes about 10sec.

gertvdijk · 2014-12-10T21:57:23Z

No problem here either. Compared to other cards/tokens it's slow, but it works very reliably in my environment.

However, USB forwarding to a virtual machine (KVM, libvirt) made my VM crash as soon as I accessed it using any tool. I'm not sure what's going on there, but I guess this VM-passthrough is more libusb/libccid related than OpenSC. Using regular smart card forwarding should just work, by the way (unsure of non-Windows guest support).

frankmorgner · 2014-12-11T22:14:59Z

@rvalle can you test with a different token or setup?

rvalle · 2014-12-22T19:53:48Z

I finally got a real HW PC to test with. will give it a try.

rvalle · 2014-12-29T07:44:17Z

Just realized that there is now a download for OSX.

# pkcs15-init --auth-id 1 --generate-key rsa/2048 --key-usage sign,decrypt --label "SampleCARootKey"
Using reader with a card: Feitian ePass2003 00 00
Failed to generate key: Transmit failed

As in the virtual machine, I can generate rsa 1024 keys but this error comes up with 2048 keys.

I am starting to think that may be there is something wrong with my tokens: I got them direct from Feitian shop the 5x SDK.

On HW I use debian, where the distribution is very old. I will have to compile the packages.

rvalle · 2014-12-29T10:35:58Z

Yes, on a new server I can generate rsa/2048. it works.

So I didn't manage to make it work on these platforms:

Linux guest running on VirtualBOX/OSX host.
OSX

My use case is running a private certificate authority, I dont want to share the same box with other services, so, a virtual server would be convenient.

dengert · 2014-12-29T13:07:42Z

If this is a timeing problem, or problem with USB power being turned off, the OSX host controls that in both cases: VirtualBOX/OSX host and OSX native. So I would point the finger at OSX, or the pcscd verison used on OSX.

You used the terms "new server" and "debian, where the distribution is very old", this does not help very much. Giving versions of hardware, OS (both host and virtual) , pcsc-lite (both host and virtual) , VirtualBox and opensc (virtual) in the future would help.

rvalle · 2014-12-29T14:12:15Z

Sure.
If you need an environment where to reproduce the problem here are the versions you need:

HOST: OSX 10.9.5 (MacBook Pro, late 2013).
Hypervensor: VirtualBOX 4.3.20
Debian 7 with: OpenSC 0.14.0, ccid-1.4.18, pcsc-lite-1.8.12

dengert · 2014-12-30T14:36:39Z

Maybe someone with a MacBook can test this, I can not.

The epass2003 I have has a LED in it, and is always on. If the issue is the USB gets powered down, does the LED goo off?

Something simple to try is a a USB hub that has a LED to see if it stays powered up, and if the hub
has an external power try the hub with that too.

FWIW, my ePass2003 LED keeps ON (and heats up a little) when I plug it into a USB power port when my notebook is OFF.

In a broader scope, isn't this discussion is a bit pointless in OpenSC here? I see USB level issues which are known with VirtualBox and other hypervisors. I'd report it there, like this one and this one.

@rvalle I'm curious why it won't work natively on your Mac OS X host. Did you create a proper pkcs15 profile on the card? I see the same errors when erasing the card, but failing to initialize the token properly before generating a keypair. E.g. this should work, but would fail if you'd omit the second line.

pkcs15-init --erase-card
pkcs15-init --create-pkcs15 --profile pkcs15+onepin --label "My ePass2003"
pkcs15-init --auth-id 1 --generate-key rsa/2048 --key-usage sign,decrypt --label "My first RSA key pair"

(as explained in this blog article).

Just wanted to point out this because ePass2003 tokens out of the box don't work with OpenSC, neither those initialized with the proprietary Feitian software.

rvalle · 2014-12-30T15:26:22Z

With regards to OSX, yes, I followed those steps. I add another parameter when initializing the token which is: --use-default-transport-key

I remember that in both cases (OSX & Virutal Machine) the LED blinks and when it fails (2048 bit keys) it remains off for some seconds before failing. Sometimes (or every time, I don't remember) the token is not detected after the error and software/hardware needs to be restarted/replugged.

With OSX native I can continue testing if you want. However I am unsure of which are all dependencies, I updated OpenSC to the last version 0.14.0 but I have had other tokens working here your years and I don't know if the required libraries are same as Linux. If you point me in the right direction I will do more testing. Meanwhile I will try the HUB and see if that changes something.

Also, If any in the dev team is willing to test but has no Macbook I could open an SSH tunnel into the Virtual Machine. Yes, it might be an USB issue, yet is making your software fail, you might want to check if there is an easy workaround.

I do a lot of USB/VirtualBox in this macbook, usually without much trouble, that includes using programmers for micro controllers and even an USB oscilloscope. Should be feasible to make it work.

Just let me know if I can help somehow.

LudovicRousseau · 2014-12-30T17:42:17Z

It looks like the problem is not in OpenSC but in a low level layer.

Can you detail (OS, pcsc-lite version, libccid version, virtual machine or not):

the configuration(s) that work

@rvalle you can get pcscd debug on Mac OS X. For that

connect your smart card reader
kill any running pcscd process
start pcscd in a terminal using "sudo LIBCCID_ifdLogLevel=0x000F /usr/sbin/pcscd -dfa"

Then attach the last ~50 lines of logs.

rvalle · 2015-01-04T17:46:42Z

@LudovicRousseau here you have the logs.

If it is a HW issue, you have workarround it in the past.
I have had tokens running on this MacBook since I got it.
The older token: epassPKI is working fine generating RSA 2048, while the epass2003 fails.

So I have captured both logs, from working and failing token, here are those:

epass2003RSA2048KeyGenFailure: http://pastebin.com/nwvAEzZf
epassPKIRSA2048KeyGenOK: http://pastebin.com/3D2SXrdB

the epassPKI is super-low, but it finally gets a working RSA2048 key. (I have verified it by using it with SSH).

rvalle · 2015-01-04T17:50:13Z

@LudovicRousseau also, for your information, not only KeyGeneration is failing on epass2003@MyMacbook.

I have also tried to use the generated RSA2048 keys on other working environments on this macbook, by using them with SSH, and I get a Signature Error like:

ssh user@server.lan
Enter PIN for '(User PIN)':
C_Sign failed: 5
ssh_rsa_sign: RSA_sign failed: unknown err

So the token is correctly sending "time extension requests" in some cases.

I guess it is the same problem you talked about in #301 (comment)

I am surprised that the same token works fine on Debian and Raspberry Pi.
How have you solved the problem described in #301 (comment) ?

rvalle · 2015-01-05T08:48:31Z

I haven't fixed anything, I have just tested on different environments.
I am, in fact, considering to deploy this token in our company, so I am an end user.
What I can do is get you similar logs on the working environments.

Could you give the serial number of failling ePass2003. Only the first 4 digits written on the USB connector YYMM. According to Feitian ePass2003 COS had an update which improved the support of 2048 certificate in Mac OS.

Currently I have got a similar problem on OSX 10.9 and 10.10 with Feitian proprietary middleware and old 1210 ePass2003. I will try with a recent one on OSX with both Feitan middleware and OpenSC and keep you informed.

The same ePass2003 is working fine with 2048 certificates on other plateforms
xubuntu 14.4 with OpenSC 0.14.0
Windows7 with both Feitan Middleware and OpenSC

My company Logidata is distributor of Feitian in France we may also help with hardware or latest beta drivers.

@marcrt I got this Feitian SDK quite recently.
The YYMM on my tokens is: 1409

@LudovicRousseau , @marcrt
Some more information on the OSX environment,
I just performed a Clean install of my Macbook with OSX 10.10.1 Yosemite: that is format the HD drive and reinstall from the scratch.
And the epass2003 continues to fail generating RSA/2048.
This time, however, the error message is slightly different:

pkcs15-init --auth-id 1 --generate-key rsa/2048 --key-usage sign,decrypt --label "My first RSA key pair"
Using reader with a card: Feitian ePass2003
Failed to generate key: Card removed

@rvalle
Firefox TLS user authentication with 2048 bits certificate works on my side (certificate generated on another environment. Same transaction was failing with old ePass2003)
ePass2003 serial nb 1409xxxx
Feitian middleware 20141209
MacBook pro with OSX 10.10.1 Yosemite
@LudovicRousseau
I agree the problem is at low level. Recent COS is necessary for 2048 operations on Mac only, less chance to get a CCID error. I am also a bit confused with apple ctkpcsd implementation compared to pcsc-lite.
What version of ePass2003 hardware did you test in http://pastebin.com/nwvAEzZf ?

rvalle · 2015-03-06T12:44:25Z

@LudovicRousseau after some correspondence with ftsafe, they seem to have fixed this problem.

FeitianSmartcardReader · 2015-08-13T08:40:33Z

@LudovicRousseau The problem has fixed in firmware, and i just check web http://pcsclite.alioth.debian.org/ccid/section.html,It showed below, could you please change status of epass2003? thanks
"The device may fail at generating keys onboard. See #301"

LudovicRousseau · 2015-08-13T14:02:24Z

@FeitianSmartcardReader have you changed the firmware release bcdDevice to a value > 1.00 to differentiate from the bogus version?

martinpaljak · 2015-08-13T14:03:27Z

Yes, this is a common problem - no change in observable attributes if behaviour changes. This is a must have.

FeitianSmartcardReader · 2015-08-14T05:44:48Z

Yes, our engineer already changed bcdDevice vaule, thanks
