Hi,
I am trying to upgrade openssl for my embedded OS platform. The one we currently use is pretty old i.e. OpenSSL 0.9.6a , but porting to Openssl 1.1.1b works fine.
I need suggestion regarding random number interface , earlier we were using RAND_METHOD.
Can I still use the same mechanism? Because I see new code rand folder contains OS specific implementation of
rand_pool_acquire_entropy
rand_pool_add_nonce_data
rand_pool_add_additional_data
As I understand , above function also needs to be ported?
Any document to start with porting random number to any platform.
Thanks
