Traditional encryption techniques have been rendered obsolete by the emergence of cutting-edge technical innovations, leaving data and pictures exposed to attackers. Hardware improvements have considerably decreased attacks on block ciphers. Modern cryptographic programmes are vulnerable to a variety of assaults, and most systems include flaws that put data security at risk. When implementing cryptographic approaches, it is imperative to have a solution that solves the trade-off between security and effectiveness. A combo of RSA, AES, & Blowfish has indeed been suggested as a solution to these problems. In this research, the drawbacks of available methods are addressed by combining various symmetric and asymmetric cryptographic techniques. Often employed for data encryption on the TLS Layer, RSA requires two unique keys to encode and decode information. The quickest algorithm is blowfish, but the most effective and reliable encryption is offered by AES. To ensure key security, the proposed approach encrypted content 3 times utilizing the three different techniques. RSA, AES, and Blowfish could be employed in tandem to alleviate the shortcomings of their individual applications, providing a practical remedy for the safety and performance tradeoff.
