Encoder Decoder Application

[titaniumtushar]

Task Description:

• Design and implement an Encoder Decoder application with a graphical user interface (GUI) using C++ or Java.
• The application should allow users to encode plaintext messages into ciphertext using various encoding algorithms and decode ciphertext back into plaintext.
• The GUI should provide an intuitive interface for users to input messages, select encoding algorithms, and view the encoded or decoded output.
• The application should support multiple encoding algorithms such as Caesar cipher, Base64 encoding, and custom substitution ciphers.

The primary goal of the project is to provide users with a user-friendly tool for encoding and decoding messages while demonstrating proficiency in GUI development and algorithm implementation.
