Hash functions play an important role in modern cryptography. They are widely used to provide services of data integrity and authentication. The hash algorithms are based on performing a number of complex operations on the input data that require a significant amount of computing resources especially when the input data are huge. Thus, hardware implementation is far more suitable, for security and performances execution issues, compared to the corresponding software implementations. Hash functions perform internal operations in an iterative fashion, which open the possibility of exploring several implementation strategies. Cryptography plays an important role in the security of data. Even though the data is encrypted it can be altered while transmitting on the network so data should be verified using a digital signature. Hashing algorithms are used to create these digital signatures for verification of the data received. Hashing algorithm like Secure Hash Algorithm-2 (SHA-2(224/256)) is designed which has a fixed output length of 512-bits.
