This research paper explores the implementation of the Caesar Cipher, a foundational encryption method attributed to Julius Caesar, covering applications in plain text, image and file-based contexts. It outlines the encryption and decryption processes for plain text, showcasing the simplicity and functionality of the cipher. Additionally, it extends its application to file-based operations, addressing scenarios requiring secure file communication. pixel - based enhance digital image security through advanced encryption techniques, including pixel manipulation and robust key management, with a user-friendly interface. The ability to employ secure communication methods and the process of rendering original messages unintelligible are known as cryptography. Caesar cipher is a method for protecting communications from dissidents by encrypting them into unintelligible form. The Caesar cipher is a type of symmetric technology that uses a secret key to transform messages. Caesar cipher has several difficulties, including ease of hacking, low security, and pattern recognition. Decrypting the entire communication is possible. All ASCII and extended ASCII characters, including alphabets, can be used to encrypt data using the Caesar cipher. This will offer an enhanced aspect of the Caesar cipher that can overcome any danger it faces. Plain Text Encryption and Decryption: The research paper details the stepwise procedures for encrypting and decrypting plain text using the Caesar Cipher, emphasizing key selection, alphabet shifting, and substitution. Practical examples illustrate the cipher's practicality and efficacy in securing messages. File Encryption and Decryption: Beyond plain text, the research paper explores the extension of the Caesar Cipher to file-based operations. It describes the process of reading content from a file, applying the cipher algorithm, and writing the processed data back to the file. This application caters to secure file communication, aligning with the principles of the Caesar Cipher. Image Encryption and Decryption: The paper aims to enhance digital image security using advanced encryption techniques. It converts images into byte data and employs pixel manipulation algorithms for encryption. Strong encryption methods, including symmetric and asymmetric encryption, are utilized along with robust key management practices. The project features a user-friendly interface for easy interaction.
