Since the dawn of internet software growth, we have resided in a digital environment fraught with cybersecurity concerns. The sophistication in today’s traditional security measures is one of the primary reasons for the increasing number of cyberattacks, thus leaking sensitive data. Encryption, which involves transforming plain text into cipher text, is important for maintaining software security and preventing the unauthorized entry of probable hackers. However, it is evident that the encryption algorithms generally have a high resource requirement in terms of memory, processing time, and electricity. This paper compares ten more common used encryption algorithms: AES, Blowfish, CAST5, Camellia, ChaCha20, DES, 3DES, RC2, SEED, and SM4. There have been evaluations under different conditions: different data types and sizes and requirements for CPU time and encryption/decryption speed. The results of these simulations have pinpointed that each of the algorithms is good enough on its own to be efficient and effective, hence helping the organizations choose the more appropriate technique for their software’s security. Therefore, this work importantly contributes to the field of cybersecurity as it adds posing of extensive examination on the most represented encryption algorithms and their performances in different situations. Organizations use the stringent encryption methods to secure their software and data which lessens the odds of cyberattack and data leak.
