openssl rsa RSA处理工具
<openssl rsa>
介绍
openssl rsa 是RSA处理工具。可以提取公钥，加解密RSA公/私钥文件（施加密码保护），格式转换，检查RSA文件完整性，输出RSA文件的modulus和components（^_^我也不知道是啥）。
语法
openssl rsa[-inform PEM|NET|DER] [-outform PEM|NET|DER] [-in filename] [-passin arg] [-out filename] [-passout arg] [-sgckey] [-des] [-des3] [-idea] [-text] [-noout] [-modulus] [-check] [-pubin] [-pubout] [-engine id]
-pubout / -pubin 指明输出文件或输入文件是公钥文件，-pubout经常用于从公钥文件中提取私钥(这句话对不对，还请大侠指点)。
