RSA
RSA非对称加密公私钥对生成，输出PEM格式的公私钥对，同时支持PKCS#1、PKCS#8密钥格式输出；生成的公私钥对，可拷贝到文本文件，保存为.key文件即可使用。
**PEM格式：**RSA公私钥对常用的编码方式，OPENSSL以PEM格式为主，相对DER可读性更强，以BASE64编码呈现；
开头类似 -----BEGIN PRIVATE KEY-----
结尾类似 -----END PRIVATE KEY-----
PKCS#8密钥格式，多用于JAVA、PHP程序加解密中，为目前用的比较多的密钥、证书格式； PKCS#1密钥格式，多用于JS等其它程序加解密，属于比较老的格式标准。 PKCS#1和PKCS#8的主要区别，从本质上说，PKCS#8格式增加验证数据段，保证密钥正确性。
