Caesar Cipher is a free and open-source Windows application that allows users to easily encrypt and decrypt text using the Caesar cipher method, by shifting each letter by a user-defined number of steps. Therefore, you can securely send private messages to a friend without worrying about someone getting ahold of the content (not without the key, at least).
Since installation is not a prerequisite, you can save the program files in any part of the hard disk and just click the executable to run.
Another possibility is to save a copy of Caesar Cipher to the USB flash disk or similar storage unit, in order to run it on any PC effortlessly and without previously installing anything.
Worth mentioning is that the program does not modify Windows registry settings, nor create extra files on the PC, leaving it clean after removal.
Straightforward interface and options
The main app window has a regular look and structure, where you can type or paste text, specify the key, and instantly generate the encrypted text. Decrypting it is just as easy. Furthermore, you can copy the encrypted text to the Clipboard for further usage. There are no other notable options provided by this software app.

We have not come across any issues throughout our evaluation, since the tool did not freeze, crash or pop up error messages. Although it is not particularly resourceful, Caesar Cipher gets the job done and can be easily used by anyone.
