安装openssl for Windows.
之后开管理员控制台,打开openSSL
我的是
C:\OpenSSL-Win32\bin\openssl.exe
生成1024位的私钥,不指定的话默认2048位
genrsa -out rsa_private_key.pem 1024
根据这个私钥生成公钥
pkcs8 -topk8 -inform PEM -in rsa_private_key.pem -outform PEM -nocrypt
之后用文件名搜索rsa_private_key.pem.这个是私钥
我的win8.1不知道为毛跑到C:\Windows\SysWOW64.
rsa_public_key.pem是公钥.复制分割线内的内容即可

java生成的密钥的第一步略有不同
OpenSSL> pkcs8 -topk8 -inform PEM -in rsa_private_key.pem -outform PEM -nocrypt
具体看那个open支付宝的链接,嘿嘿.
