Secure hash algorithms (SHAs) are important components of cryptographic applications. SHA performance on central processing units (CPUs) is slow, therefore, acceleration must be done using hardware such as Field Programmable Gate Arrays (FPGAs). Considerable work has been done in academia using FPGAs to accelerate SHAs. These designs were implemented using Hardware Description Language (HDL) based design methodologies, which are tedious and time consuming. High Level Synthesis (HLS) enables designers to synthesize optimized FPGA hardware from algorithm specifications in programming languages such as C/C++. This substantially reduces the design cost and time. In this thesis, the Altera SDK for OpenCL (AOCL) HLS tool was used to synthesize the SHAs on FPGAs and to explore the design space of the algorithms. The results were evaluated against the previous HDL based designs. Synthesized FPGA hardware performance was comparable to the HDL based designs despite the simpler and faster design process.
