This updated version allows the users of Eureka Encryption Messenger to safely and securely have a traditional terminal chat, plus transmit files.  It should be noted that this is a one to one communication, so if you want to transmit to multiple people, it will require a seperate connection for each one at different times.

This version is different from the version 3 Messenger as it is cross-compatible with Windows, Mac and Linux.   Once connected, you can begin transmitting or receiving the data without any setup.  In addition, you can reset this key at any time by using the Key exchange feature, by clicking on Keys then Exchange New Key.  You can then enter in a passphrase or click on Generate to have messenger create one for you.  Click on Send to exchange keys with the other computer.

If a firewall is installed on either machine, some configuration may be required in order for the computers to make a connection. 

One of you must first listen for a connection (referred as being the Host).  You do this by simply clicking on the Wait for Connect button.  The person who will connect with you enters your ip address (unless you have a static ip address you will need to contact the person and let them know what yours is) in the Connect to IP Address box then clicks on Connect.  Once connected, you are ready to go, and either of you can send or receive at will.  Notice the default port of 7777.  This should not be a problem, but if you need or want to use another port, change it before you connect and also let the person know about it as well.

Here's the program screen, and we'll dicuss all the various components in it.

Let's first discuss the Status area, located in the lower left hand portion of the screen.  This records all actions performed such as sending a file, receiving a file, etc.  Underneath this status box are two indicators (you will notice these once files are transmitted, etc.) that represent the sending and receiving of data. The red ones indicate the sending and the green ones the receiving.   This way you know that the connection is still active as files and so forth are exchanged.

Notice that a Recv folder was created in the folder where you are executing Messenger from.  All files transferred with this program will be placed there.  If you send a file that is the same name as one sent, it will be overwritten, so give the person time to move it before sending if required.  The process is slow, so be patient.  We are looking at ways to increase it, but with the encoding and decoding and having to receive a response back, it can take awhile for large files.  While transferring files, refrain from doing anything else until it has completed.

You can send a file by clicking on either File/Send File and select the file you want to send, or clicking on Select in the Send File section in the lower right, then clicking Send.  While the transfer is in place, do not do anything else until it has completed to ensure a complete and accurate transfer.

The middle portion of the screen is the Chat area.  Type in the box at the bottom of the area and hit enter or click on the Send button next to it to send the message.  The Chat window will display your message surrounded by < and > and messages received in plain text.  For example, if you send the message 'Are you ready?' and they respond 'Ready when you are', you will see it as:
