转自http://sqkoo.com/show/detail/298

1 生成RSA私钥：

openssl genrsa -out rsa_private_key.pem 1024


2 生成RSA公钥
openssl rsa -in rsa_private_key.pem -pubout -out rsa_public_key.pem


3 将RSA私钥转换成PKCS8格式
openssl pkcs8 -topk8 -inform PEM -in rsa_private_key.pem -outform PEM -nocrypt -out rsa_pub_pk8.pem

rsa_private_key.pem文件内容如下：
