Hi, I am beginner in openssl and I am porting openSSL-1.1.1d in vxWorks-6.9. So as suggested I have defined "OPENSSL_RAND_SEED_NONE" flag, as for vxWorks 'none' is only supported but after doing so I am observing "rand_pool_entropy_available()" returns 0 which further leads to failure. I came across that while NONE is set then manual seed and re-seed is must for the applications depend on random generator. I am very confused and as not having any openSSL experience I am not able to understand what needs to be done to resolve this issue. In my project many applications are using openssl APIs, So do I need to call RAND_add() in all applications where some random generation is being done? or is there anything else I can do to provide the seeds? Please help. Thanks in advance. -- Sent from: http://openssl.6102.n7.nabble.com/OpenSSL-User-f3.html
