2015年11月14日 (土) 20:16時点における最新版

RedHat/CentOSのOpenSSLには、FIPSのパッチが入っていて、遅いようです。CentOS環境で、比較しました。

読み方

OpenSSL
おーぷん えすえすえる

概要

FIPS無しのOpenSSLが必要だったので、自分でビルドしました。 比較するバージョンが違っていますが、以下のバージョンを比較しました。

  • 自分でビルドした 1.0.1p
  • 自分でビルドした 1.0.1p fips
  • OpenSSL 1.0.1e-fips 11 Feb 2013

結論

自分でビルドした 1.0.1p のほうが 1.0.1e-fips よりと若干高速でした。

ビルド方法

FIPS無効

tar zxfp openssl-1.0.1p.tar.gz
cd openssl-1.0.1p
sudo yum install zlib-devel
sh config zlib
make

FIPS有効

先にfips用のライブラリをビルドします。

wget https://www.openssl.org/source/openssl-fips-2.0.10.tar.gz
tar zxfp openssl-fips-2.0.10.tar.gz
cd openssl-fips-2.0.10
sh config zlib
make
sudo make install
tar zxfp openssl-1.0.1p.tar.gz
cd openssl-1.0.1p
sudo yum install zlib-devel
sh config zlib fips
make
