Please use the CrypTool software to decrypt two messages, files with messages are below. File 1 uses a cipher, which is encrypted with the Caesar method. Use the analysis tools in the CrypTool software to determine the shift amount and then decrypt the message. Save the decrypted message along with the frequency analysis figures.

File 2 has a message encrypted using the Vigenere method. Once again, use the analysis tool to find the encryption key to perform the decryption. The key may be 3 to 5 letters long. With each selected key size and subsequently the identification of the key (using the analysis tool), you need to decrypt the message and find out the decrypted message make sense. If this is not the case, you should try another key size and continue the same process until the decrypted message makes sense. Save the key, decrypted message, frequency analysis for Vigenere method.
