Use CrypTool to Encrypt and Decrypt messages
1) Download the CrypTool from the web. You can find it here: http://www.cryptool.org/en/ct1-download-en. (You can see a demonstration of this tool in LabSim 2.3)
2) Download this file, decrypt it and reveal the hidden message: Cry-RC4-message.zip
Tip: You will have to figure out the correct settings for the analysis to work.
