Cryptography, Hash Algorithm, MD5, RSA. 1. INTRODUCTION Cryptography is the practice of hiding the message in a secret code. In this modern world, to provide integrity, authenticity of the messages send over the communication channel needs to be provided with security. Features of using cryptography are privacy of the data only the intended receiver can read the data send from the …

Encryption and decryption algorithm’s security depends on the algorithm while the internal structure of the rigor of mathematics, it also depends on the key confidentiality. Key in the encryption algorithm has a pivotal position, once the key was leaked, it means that anyone can be in the encryption system to encrypt and decrypt information, it means the encryption algorithm is useless
