of_sec_sha256
SHA-224/256 engine
Maturity fpga-routedTargets FPGA + ASICDifficulty EasyPriority 1
SHA-224 and SHA-256 core with message padding, multi-block streaming and saved context for interleaved sessions.
FPGA-routed. The block meets timing on a routed FPGA netlist at a stated clock and its testbench passes on that netlist. It has not yet run on a board or in silicon.
