Hello,<br>
<br>
C_GenerateKeyPair on hardware ACS CryptoMate (T2),
<pre>idVendor: 0x072F
idProduct: 0xB106
</pre>
always fails with bit size > 3328 (... 4096), it succeeds <=
3328.<br>
As comparison, C_GenerateKeyPair on predecessor hardware <a class="gmail-m_5203268264300961805moz-txt-link-freetext" href="https://pcsclite.alioth.debian.org/ccid/shouldwork.html#0x072F0x90DB" target="_blank">https://pcsclite.alioth.<wbr>debian.org/ccid/shouldwork.<wbr>html#0x072F0x90DB</a>
takes about 3-4 minutes for 4096 bit key pair to complete (with same
ccid-git, invoked through scriptor) and #0x072F0xB106 seems to be
slower,<br>
thus my assumption, it may be something time-related (or a bug in
card operating system?).<br>
<br>
Occasionally #0x072F0xB106 also shows some other strange behavior
like starting the Linux-User-Logout-countdown (Kubuntu 16.04 xenial)
after plugging out/removing the USB token.<br>
And once, after a failed C_GenerateKeyPair, card contents were
erased.<br>
<br>
My trial to change 'TIME_BEFORE_SUICIDE' from 60 to 300 and manually
installing 1.4.26 libpcsclite and pcscd ended in screwing my system,
then back with 1.8.14, omitting --auto-exit from pcscd start params
didn't change the failure issue.<br>
I hope, the following information is complete and a solution is
close?
