Hi,

that's right !
A workaround would be to configure the IBMCA engine into openssl (openssl.cnf).
However, as the Polyakov code directly make use of the CPACF instructions we 
will end up with about
50 % performance degradation compared to the 'longer' way through the libica 
API for small payloads.

For the asymmetric case, when no CEX5 cards are available, we will still
have a factor ~4. You remember the 'bn_mult_add_words' improvements,
right ?
