SSLSocket

An SSL socket server and client in JAVA

Installation

git clone https://github.com/williamswhy/SSLSocket.git

Usage

Compile & prepare files

mkdir bin
javac -d bin src/client/*.java
javac -d bin src/server/*.java

Start server & client

server:

java server.SocketListener

client:

java client.SocketClient [address] [port] [message]

Generate SSL

Create a server keystore file:

keytool -genkey -keystore sslserverkeys -keyalg RSA

Export the key as a cert:

keytool -export -keystore sslserverkeys -file cert.cer -keyalg RSA

Add the cert to the trust store of the client:

keytool -import -keystore sslclienttrust -file cert.cer -keyalg RSA

NoSuchAlgorithmException in Client and Server

Hey,
thanks for the recent commit.

Unfortunately i can't get it to work now.
On both ends (server and client) I get the following exception:

java.net.SocketException: java.security.NoSuchAlgorithmException: Error constructing implementation (algorithm: Default, provider: SunJSSE, class: sun.security.ssl.SSLContextImpl$DefaultSSLContext)

I downloaded the sslclienttrust and sslserverkeys from one of your previous commits.
I initialized them like this:
In Server:

System.setProperty("javax.net.ssl.keyStore", "sslserverkeys");
System.setProperty("javax.net.ssl.keyStorePassword", "123456");

In Client:

System.setProperty("javax.net.ssl.trustStore", "sslclienttrust");
System.setProperty("javax.net.ssl.trustStorePassword", "123456");

With your recent readme i can't figure out how to create the required files for client and server.
Could you @mention some information about the proccess, if you're not updating this repo anymore.

Thanks in advance :)
