Abstract
This paper gives a complete examination of multiple modes of Advanced Encryption Standard (AES) algorithms, concentrating on their performance features and security consequences. A comparative analysis was conducted on all modalities to determine the fastest and most efficient option in terms of throughput. The Electronic Code Book (ECB) mode has been determined to be the fastest one thorough experimentation and analysis. However, it is important to note that this mode may have security weaknesses due to its block-independent nature. Conversely, Cipher Block Chaining (CBC) mode offers greater security through chaining techniques and competitive throughput. the findings underline the significance of balancing speed and security factors when selecting an AES encryption option. A comparative analysis was conducted on all modalities to determine the fastest and most efficient option in terms of throughput. Integration of Simple Mail Transfer Protocol (SMTP) with the Gmail API provides secure key distribution, boosting secrecy and integrity in email communication. This research gives significant insights for enhancing AES encryption and strengthening data security against evolving cyber threats.
