This project implements two cryptographic algorithms: RC4, a stream cipher, and AES (Advanced Encryption Standard), a block cipher. Both algorithms are widely used in cryptography for their unique ...

With the recent improvements in cryptanalysis, more applications have started to use Advanced Encryption Standard (AES) instead of Data Encryption Standard (DES) to protect their information and ...

Abstract: Due to the advancement of technology, information security and user privacy have become a critical issue resulting in the use of various encryption techniques. Especially with the increasing ...

AES 128 is a symmetric encryption algorithm that securely transforms plaintext data into ciphertext using a key. It operates on fixed-size 128-bit data blocks and performs a series of substitution, ...

Abstract: With the rapid development of information technology, data security issues have become increasingly prominent. As one of the most widely used symmetric encryption algorithms currently, AES ...
