Subject: As "openssl speed" does not support GOST parameters,
X-Git-Tag: v3.0.0~326
X-Git-Url: http://www.wagner.pp.ru/gitweb/?a=commitdiff_plain;h=50655599e6063059d00e2be8bfeb25ce93cf6fef;p=openssl-gost%2Fengine.git

As "openssl speed" does not support GOST parameters,
benchmark is done separately.
