Analysis of Key Based Cryptographic Algorithms and its Applications

Information security is the process of safeguarding data. It safeguards its availability, privacy, and integrity. The capacity to secure data from attacks, as well as efficiency and speed are the two key features that separate one cryptography algorithm from another. Security is the most difficult issue in the present world, and the various security dangers in data security must be avoided in order to provide consumers with more privacy while still permitting high information availability and Integrity. Data encryption employing various data encryption techniques will increase the security of data transmission. This paper primarily focuses on a comparative analysis of symmetric algorithms (AES, DES, Ceaser Cipher, Stream Cipher) and asymmetric algorithms (Diffie Hellman, RSA), and also file and image encryption using symmetric algorithms.
