最近要在新项目中使用支付宝钱包进行支付,所以要调研对接支付宝的接口,支付宝开放平台采用了RSA安全签名机制，开发者可以通过支付宝 公钥验证消息来源，同时可使用自己的私钥对信息进行加密,所以需要在本机上生成私钥和公钥 ...
由此需要开发者在本地上使用openssl来生成私钥和公钥
由于mac 自带openssl工具,所以不用像windows那样要下载安装openssl工具
生成私钥公钥很简单:只要三句命令就可以搞定
打开openssl : $openssl =====>> OpenSSL>
- genrsa -out rsa_private_key.pem 1024 ======>> Generating RSA private key, 1024 bit long modulus
