Julius Caesar used to apply a simple trick in sending his protected messages of military significance. The trick, coined as 'Caesar cipher', is one of the simplest and widely known encryption techniques. The writer took the liberty to apply this technique in his program called 'FingCryptor'.
"K.I.S.S. = Keep It Stupid, Simple"
In this spirit, the writer has developed this application in order to assist him in his passwords management. The Wikipedia article on Caesar Cipher [1] is the main source as the guide to develop this application. The GUI - graphical user interface, is designed on Qt 4, whereas the codes for this application are written in C++. The writer is also planning to expand this application and making it more complex albeit low security in the future.
The following image shows how to understand Caesar cipher at its fundamental principle - i.e. shifting any letter three steps backwards.

The main advantage of FingCryptor: the writer extended the use of this operation on all ASCII characters e.g. '@', '#', '?' etc, including numbers from 0 to 9.
Images 2 and 3 show the usage of FingCryptor.

REMINDER / WARNING:
- For Windows only. (Linux version will be made available in the next development)
- This application is NOT intended for any high security objective.
- The writer is NOT liable for any security breach - i.e. deciphering by a third party etc.
