The cryptographic cipher is the terminology used for securing the web user data over the network. It is closely related to the discipline of cryptology and cryptanalysis. Using mathematical equations, the cryptography make sure the data when transferred over network is not altered. The important things for the study of mathematical equations on data security, it is almost not possible to break the encryption algorithm without knowing the correct key value. This paper focuses on the study of cryptographic algorithms and its functioning over the data transmission. The throughput is calculated for encryption algorithms during encrypting of text data in different time period and it is found that the Diffie-Hellman Key Exchange Algorithm shows better performance as compared to other studied algorithms.
