 ?二、RSA密钥生成命令 ?1、生成RSA私钥 ?openssl>openssl genrsa -out rsa_private_key.pem 1024 ???得到exponent: 10001 ?2、生成modulus: ?openssl>openssl rsa -in rsa_private_key.pem -noout -modulus ???3、生成RSA公钥 ?openssl>openssl rsa -in rsa_private_key.pem -pubout -out rsa_public_key.pem ?4、将RSA私钥转换成PKCS8格式（==========java使用===========） ?openssl>openssl pkcs8 -topk8 -inform PEM -in rsa_private_key.pem -outform PEM -nocrypt ?注意：“>”符号后面的才是需要输入的命令。
