It provides functionality to encrypt a message and decrypt an encrypted code back to the original message.\n\n## Features\n\n- **Encryption**: The program takes a user input message and encrypts it using a predefined key-value pair for each alphabet character. It converts each character of the message to its corresponding integer value.\n- **Decryption**: The program allows the user to input an encrypted code and decrypts it back to the original message using the reverse mapping of the key-value pairs.\n- **Customizable Key**: The key-value pairs for encryption and decryption can be customized according to specific requirements.\n- **Input Validation**: The program handles input validation to ensure that only valid messages and encrypted codes are accepted.\n\n## Usage\n\n1. **Compile the Program**: Compile the Java program (`EncryptionDecryption.java`) using any Java compiler.\n\n2. **Run the Program**: Execute the compiled program to start the encryption and decryption process. Follow the instructions provided in the console.\n\n3. **Input Message**: Enter the message that you want to encrypt. You can include any characters, including whitespace.\n\n4. **Encrypted Code**: The program will generate an encrypted code based on the input message and display it to the user.\n\n5. **Input Encrypted Code**: Enter the encrypted code when prompted by the program.\n\n6. **Decrypted Message**: The program will decrypt the encrypted code and display the original message to the user.\n\n## Key-Value Pairs\n\nThe encryption and decryption process relies on key-value pairs for each alphabet character. By default, the program provides the following key-value pairs:\n\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fkrishanmurariji%2Fencryption-decryption","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fkrishanmurariji%2Fencryption-decryption","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fkrishanmurariji%2Fencryption-decryption/lists"}
