Subject: More sensitive constant timing test
X-Git-Url: https://git.codecow.com/?a=commitdiff_plain;h=72f7108a5a8c9315aaca0db6dede0b31fbaca987;p=Monocypher.git

More sensitive constant timing test

32 bytes buffers weren't big enough to make a difference if crypto_memcmp
and crypto_zerocmp don't run in constant time.  Increased to 64Kib instead.
