Description :
Now you can use this little app for securing your conversation and messages, that needs to be travel through places that are vulnerable to intruders and hackers that can modify your message contents and forwards this modified message to your friends or colleagues as it seems it is sent by you! This little app is developed solely in java and it provides a way to encrypt (encode) or decrypt (decode) the message that is somehow very difficult to crack and extract the sensitive information.Algorithm Used :
The app uses a basic enciphering technique called Caesar Cipher that uses the substitution cipher to change the plaint text according to the defined key! Same is used for decoding a encrypted message to get the original message but in opposite direction.Usage Guide:
Initial Interface:
The window up shows the main frame of the application. At the beginning all the fields are resent to contain no values.
Encoding a message:
As you can see, a plain text message must be written without spaces in the "Encrypt message" field at the time of sending the message and a key value must be provided to encode the message using substitution algorithm(key) the key must also provided to the receiver at the receiving end to decrypt or decode the encoded message to get the plain text.
Decoding a message:
A key must be provided to the receiver to decode the message back at original text. As you can see, at this time, the coded message is written in the "Decrypt" field and also a key is provided to get the original message back. Both sender and receiver system must have the software running on their machines.
Advantages of using Encryption:
- Provides Security to the most sensitive information.
- Provides secrecy to the messages.
