制作SSL证书-keytool命令

生成服务器密钥库和证书，客户端导入服务器证书：

 

1、生成密钥库（自签名的证书和私钥）

keytool -genkey -alias sksalias -keyalg RSA -keystore skeystore.jks  

密钥库和密钥库别名都需要密码，用时也需要     

Enter keystore password:

Enter key password for <ksalias>

查看密钥库

keytool -list -v -keystore skeystore.jks

2、导出密钥库公钥、信息等到证书中

keytool -export -alias sksalias -keystore skeystore.jks -storepass 123456 -file scert.cer

3、建立信任密钥库（将服务端证书，导入到客户端的信任密钥库中）

keytool -import -alias  sksalias  -file scert.cer -keystore ctruststore

信任密钥库truststore也需要密码，但别名不需要密码

//truststore也是密钥库，只是少了私钥

Enter keystore password:

查看信任密钥库       

keytool -list -v -keystore truststore

keytool,可以转换，pem，直接导入pem的。ie，firefox也可以转换。

同理，生成客户端的密钥库和证书，服务器端导入客户端证书。

keytool -genkey -alias cksalias -keyalg RSA -keystore ckeystore.jks

keytool -export -alias cksalias -keystore ckeystore.jks -storepass 123456 -file ccert.cer

keytool -import -alias  cksalias  -file ccert.cer -keystore struststore

1,用回调syslof4j的getsocket，然后socket.handshake，会卡死

2,用这个测试，也会卡死，必须server端，先开始handshake才行，或者他们之间发送消息（这样测试就会多

一条记录不好），有待深入探讨原因。
