Hello, I tried to answer the questions in between On Wed, 9 Feb 2000, kefren wrote: David wrote: Some of the crypto functions may require a significant increase in the WWT on the reader. If you let me know what reader you are using I can see if this will be a problem and fix it before it exists. Could you please explain me what "WWT" stands for, because I don't understand what the problem is. However, I'm using a Towitoko's CHIPDRIVE. WWT is working waiting time. This is the time it takes for the card to respond. On some crypto functions this might take along time causing a timeout. By adjusting the WWT you can avoid this. Just 'cause you could help me, I'm having troubles to let RSA work on the Card, and I'd be very happy if anyone could take a look at this URL: http://smartie.austin.apc.slb.com/forums/cybaccmisc/62.html#1 where I reported the problem. Furthermore, I need some elucidations about the transition from the old pcsc-src-0.8.9's C++ structure to the new pcsc's C structure. . Where has it ended the RESOURCEMANAGER class ? . Didn't you want to be compliant with PCSC/Winscard API ? . It provides separate classes for SCard, CryptKey, etc.., doesn't it ? (however, maybe I lost some important messages from you mailing-list, and misinterpreted the overall problem). The pcsc-lite uses C function calls. The reason for this is that most programs under Unix use C instead of C++ and this makes the calling conventions much easier. The Microsoft class definitions for the service providers are completely different than what is implemented under Windows. The IS_FileAccess is just a list of C functions that I defined which are very similar to those under Windows but use C instead. I would suggest using these and creating your own functions. Also, if you are looking to do crypto now you could use OCF which is in Java - I have written a layer that interfaces between OCF and pcsc-lite for Linux. You can use the crypto under OCF if you want. If you define the C functions let me know and I will document them. I don't suggest using pcsc-0.8.9 since I will no longer distribute it. It is way too bulky and non portable. A related me-uderstanding problem: what do they mean the prefixes IS_FileAccess, etc.. which I find on some (don't remember which one) card-driver ? BTW, the REAL problem, here, is: if I go on and write some code (I'm thinking to modify slb_cfaccess as a starting point), shoud I use . this-scard-hContext-Transmit(...) OR . SCardTransmit(hContext, ...) ? I would use the SCardTransmit. Download pcsc-lite from the web site and take a look at the API document under docs directory. It is pretty easy to use.

Re: R: MUSCLE SSP for Cyberflex
As David pointed out, WWT is work waiting time. See 7816-3/8.2. It's the amount of time the terminal should wait before deciding the card isn't going to respond. It is normally 1 second for cards with default timing, such as Cyberflex. Every time you call apdu.waitExtension() it resets the timer, so you can sprinkle these through the code, but Cyberflex is so slow you have to put them in every few lines. Or you can increase WWT by specifying non-default timing in your atr. Problem with this is that most terminals seem to ignore WWT. Here is an atr for Cyberflex that specifies a four second WWT: 3b 97 94 40 28 57 65 62 63 61 72 64 T=0 TA1=94 TD1=40 TC2=28 7 historical bytes: W e b c a r d 103 etu = 372 F / 1 D * 3.58 f 3990 cwt = (960 * 40 WI * 372 F) / 3.58 f / 1000 You can change the number of historical bytes, which is given in the bottom nibble of the second byte. Remember that all but the last two historical bytes are specified in the "set java atr" apdu, whereas the last two are specified in the exception thrown by your applet's main() method. *** Linux Smart Card Developers - M.U.S.C.L.E.
