I will try to explore more on AF_ALG , in between please can you also provide information regarding below ? #1: how openssl communicates to crypto h/w using PF_ALG #2: How man algorithms are supported? #3: are there any samples to get start with. but if you can provide some info regarding cryptodev-linux from the openssl prospect it will be more helpful.
