iOS 使用OpenSSL库

iOS 使用OpenSSL库

国外的大神已经搞了一个动态编译好的脚本git地址为：https://github.com/x2on/OpenSSL-for-iPhone

按照 工程的readme执行编译即可

编译完会生成 include和lib文件夹

include文件夹是头文件，lib是静态库，把这两个文件夹拖进项目 

将include文件夹拖到Build Settings-> Header Search Paths 目录下

即可。

生成RSA私钥

openssl genrsa -out rsa_private_key.pem 1024

生成RSA公钥

openssl rsa -in rsa_private_key.pem -pubout -out rsa_public_key.pem

查看公钥 内容

cat rsa_public_key.pem
