The size of the key used determines how the RSA algorithmis evaluated. In this study, a Python implementation of the RSA algorithm with varying key sizes is presented, and the performance in terms of key generation, encryption, anddecryption time is examined. Tables and graphical representations are used to display theresults.The processes of encryption, decoding, key creation, and mathematical principles are covered. System specs are used to compare various RSA keys. Various key sizes andpre-made graphs for encryption time, decryption time, and security strength are used to assess performance. The use of common cryptographic libraries for Python imple-mentation is also covered.In order to create a more secure RSA algorithm, this researchstudy attempts to modify the RSA algorithm.RSA cryptosystem algorithm is widely usedcryptographic algorithm in network security but it has problem of integer’s factorisation for small numbers. This study presents and compares a number of RSA cryptosystemimprovements that aim to increase security and expedite the encryption and decryption process.
