fanquake	4fcfcc294e	random: stop retrieving random bytes from OpenSSL ... On the ::SLOW path we would use OpenSSL as an additional source of random bytes. This commit removes that functionality. Note that this was always only an additional source, and that we never checked the return value RAND_bytes(): https://www.openssl.org/docs/manmaster/man3/RAND_bytes.html RAND_bytes() puts num cryptographically strong pseudo-random bytes into buf.	2019-11-18 08:56:40 -05:00
