Public bug reported: == Comment: #0 - Bastian Pfeifer <bastian.pfei...@de.ibm.com> - 2016-07-29 09:07:47 == ---Problem Description--- 'Libica' library versions >= 2.6.0 implement a new DRBG (Deterministic Random Number Generator) with a unnecessary stiff reseed limit leading to performance degradation (factor >20) for RSA encryption via opencryptoki. A patch is already upstream and can be found under this commit: https://sourceforge.net/p/opencryptoki/libica/ci/3bcd3efb0aff364515ab9b3c39dd68fbbb1534d0/
It will fix the issue + we will get a great performance improvement for the RSA encryption via opencryptoki's ICA-TOKEN.
