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. --- src/random.cpp | 4 ---- 1 file changed, 4 deletions(-) (limited to 'src/random.cpp') diff --git a/src/random.cpp b/src/random.cpp index 8bdf45ef67..d418740813 100644 --- a/src/random.cpp +++ b/src/random.cpp @@ -495,10 +495,6 @@ static void SeedSlow(CSHA512& hasher) noexcept GetOSRand(buffer); hasher.Write(buffer, sizeof(buffer)); - // OpenSSL RNG (for now) - RAND_bytes(buffer, sizeof(buffer)); - hasher.Write(buffer, sizeof(buffer)); - // High-precision timestamp. // // Note that we also commit to a timestamp in the Fast seeder, so we indirectly commit to a -- cgit v1.2.3
