        abstract = {An improved multi-layered encryption framework with dynamic key generation from user-defined passwords is presented in this paper. It combines traditional cryptographic algorithms with contemporary encryption methods and image steganography. Adaptive text padding, a password-derived Caesar cipher with rotating keys, a dynamic Hill cipher with password-generated matrices, matrix transposition, deterministic scrambling, AES-256 encryption, and LSB steganography are the seven layers of security architecture used in the proposed system. In contrast to conventional fixed-key systems, this framework uses seeded randomization and SHA-256 hashing to create unique encryption keys from user passwords, offering individualized security while preserving cryptographic strength. Effective resistance to frequency analysis and statistical detection techniques, improved security through password-based key derivation, and successful encryption and decryption with 100% data recovery accuracy are all demonstrated by the experimental results.},
