基于ssl双向认证的详细例子

产生服务端证书库
keytool -genkey -alias serverkey -keystore kserver.ks
产生服务端私有密匙
keytool -export -alias serverkey -keystore kserver.ks -file server.crt
产生服务端公有密匙
keytool -import -alias serverkey -file server.crt -keystore tclient.ks
产生客户端证书库
keytool -genkey -alias clientkey -keystore kclient.ks
产生客户端私有密匙
keytool -export -alias clientkey -keystore kclient.ks -file client.crt
产生客户端公有密匙
keytool -import -alias clientkey -file client.crt -keystore tserver.ks
删除服务端证书库
keytool -delete -alias serverkey -keystore kserver.ks -storepass 123456
删除客户端证书库
keytool -delete -alias clientkey -keystore kclient.ks -storepass 456789
删除后，必须手动删除这些文件，以便重复操作

具体过程如下：
D:\>keytool -genkey -alias serverkey -keystore kserver.ks
