RSA加密解密

１．什么是公钥加密私钥解密
简单一点来说一般加密解密都用的是同一个秘钥或者根本不用，而这里采用的是加密用一个秘钥，解密用另一个秘钥且能解密成功．这就属于不对称加密解密算法的一种了．

２．公钥秘钥的生成（可以git中生成）
由于这种加密方案，公钥秘钥是成对的，所以需要一些工具生成

利用　openssl　生成公钥私钥
生成公钥： openssl genrsa -out rsa_private_key.pem 1024
生成私钥: openssl rsa -in rsa_private_key.pem -pubout -out rsa_public_key.pem

RSA密钥生成命令

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
将RSA私钥转换成PKCS8格式
openssl pkcs8 -topk8 -inform PEM -in rsa_private_key.pem -outform PEM -nocrypt -out pkcs8.pem

注意：“>”符号后面的才是需要输入的命令。
