rsa_cgo's Introduction

关于rsa 签名 使用 cgo (openssl) 和golang 原生库 对比

运行

go get github.com/Bulesxz/rsa_cgo

go test -bench="."

测试环境:

硬件概览:
  型号名称:	MacBook Pro
  型号标识符:	MacBookPro13,2
  处理器名称:	Intel Core i5
  处理器速度:	3.1 GHz
  处理器数目:	1
  核总数:	2
  L2 缓存(每个核):	256 KB
  L3 缓存:	4 MB
  内存:	16 GB

os: osx 10.12.3

openssl: OpenSSL 1.1.0f  25 May 2017

golang: go version go1.8.3 darwin/amd64

经过测试 发现cgo openssl 的性能是 golang 的 5倍左右 ,5倍!!!!!

BenchmarkCgoRsa-4          10000            122419 ns/op

场景应用

使用golang rsa 签名的 高并发 程序,比如聚合支付相关(支付宝API)

注意

本人的openssl 安装在 /usr/local/Cellar/[email protected]/1.1.0f/ 不在此目录的可以视情况而改动 makefile
