Rätsel

Rätsel is German for Enigma. Rätsel is an encryption tool that can take in messages, encrypt them for transmission, then decrypt messages we get from others.

• Messages can be encrypted
• Encrypted messages can be decrypted provided the encyption key and date are passed in
• Encrypted messages can be cracked without the encryption key

• Visit the Wiki to find out how to make use of this project.

To utilize the functionality of this tool, on command line, run the following:

• To encrypt, run encrypt <file> [<output>]
• To decrypt, run decrypt <encrypted-file> [<output>] <key> <date>
• To crack, run crack <encrypted-file> [<output>] <date>

• Suppose we have a text file in a lib directory test.txt with the content below: hello hello ..end..
• On running encrypt with our output as new.txt encrypt lib/test.txt lib/new.txt
• The result will be 6a43a6zv h7ow7w527q
• Running decrypt and passing the output file, encryption key and date, we will then have: hello hello ..end..
