Android实现ssl双向验证

Android实现双向验证
前言

    Android端实现双向认证的难点主要在于Android接受的证书格式是BKS,而一般提供的证书不包含此格式,需要手动转换
    转换之后如果请求不了,表现为握手失败(Handshake failed),则一般是证书转换错误
    网上有一大堆转换方法,有的虽能正常生成BKS证书,但还是导致握手失败,推测应该还是转换方式有误
    在这里提供一种自己亲自试验过能正常转换的方法供大家参考

证书转换
使用转换工具

    在这里提供一个比较好用的转换工具Portecle
    下载完后解压双击start.bat即可使用,至于详细使用请自行百度
    使用此工具可以很方便地将jks转为bks

通过openssl和keytool转换

    openssl可以到官网下载,openssl暂时没有windows版,大伙可以在此处下载Win32OpenSSLwindows版本
    下载完记得配置环境变量,同时也记得配置jdk的环境变量,因为后面需要用到keytool命令
    现在假设你拿到了客户端证书client.crt和client.key(或者client.pem和client.key)
    通过以下命令生成pfx文件,期间会让输入密码,输入你想要的密码即可,假如这里输入的是123456

    openssl pkcs12 -export -out client.pfx -inkey client.key -in client.pem
    或者
    openssl pkcs12 -export -out client.pfx -inkey client.key -in client.crt

    执行成功则可以看到client.pfx文件,接着再执行如下命令

    keytool -importkeystore -srckeystore client.pfx -destkeystore client.jks -srcstoretype PKCS12 -deststoretype JKS

    执行成功即可看到生成了client.jks
    拿到生成的jks就可以通过Portecle工具转换成bks了
