java - 在握手之前解密从 tls 上的 websocket 客户端接收到的字节

解决了！解密委托给 SSLSocket 类。如果有人想在这里做这些步骤。

将 CA 颁发的证书和私钥导出到 p12 文件

openssl pkcs12 -export -in certificate/path/certificate.crt -inkey /path/privatekey/private.key -out filep12.p12 -name your_domain -CAfile /path/ca.crt -caname your_ca

Java 密钥库

keytool -genkey -alias your_alias -keyalg RSA -keystore name_store.jks -keysize 2048

输入密码（your_password）并确认后

keytool -importkeystore -srckeystore name_store.jks -destkeystore name_store.jks -deststoretype pkcs12 -srcstorepass your_password

keytool -delete -alias your_alias -keystore name_store.jks -storepass your_password

keytool -importkeystore -deststorepass your_password -destkeypass your_password -destkeystore name_store.jks -srckeystore filep12.p12 -srcstoretype PKCS12 -srcstorepass your_password -alias your_domain

your_alias 不能与 your_domain 相同或相似，在每个步骤中都要求输入密码 (your_password) 始终相同，以便在解密时没有填充错误

} 

}`

其他的，到websocket的连接应该是这样的 wss://your_domain:port websocket url中不能输入IP地址，必须用CA颁发的证书中注册的域来完成

使用解密的字节，我可以继续使用 RFC6455 协议。这只是我所做的测试，显然对于套接字应用程序，此外，还需要异步处理连接到服务器的客户端。我使用 ExecutorService 类执行此操作，但这是另一个主题
