wolfssl implemented AES ECB/CBC/CTR/GCM/CCM in RISC-V assembler, achieving massive speed improvements on boards with such CPUs. Benchmarking on a Sifive Unleashed (oldest Linux-capable RISC-V board), results are: No optimization: wolfCrypt Benchmark (block bytes 1048576, min 1.0 sec each) RNG 10 MiB took 1.772 seconds, 5.644 MiB/s AES-128-CBC-enc 5 MiB took 16.264 seconds, 0.307 MiB/s AES-128-CBC-dec 5 MiB took 16.314 seconds, 0.306 MiB/s AES-192-CBC-enc 5 MiB took 19.460 seconds, 0.257 MiB/s AES-192-CBC-dec 5 MiB took 19.480 seconds, 0.257 MiB/s AES-256-CBC-enc 5 MiB took 22.633 seconds, 0.221 MiB/s AES-256-CBC-dec 5 MiB took 22.715 seconds, 0.220 MiB/s AES-128-GCM-enc 5 MiB took 16.324 seconds, 0.306 MiB/s AES-128-GCM-dec 5 MiB took 16.450 seconds, 0.304 MiB/s AES-192-GCM-enc 5 MiB took 19.487 seconds, 0.257 MiB/s AES-192-GCM-dec 5 MiB took 19.621 seconds, 0.255 MiB/s AES-256-GCM-enc 5 MiB took 22.644 seconds, 0.221 MiB/s AES-256-GCM-dec 5 MiB took 22.805 seconds, 0.219 MiB/s [...] Enabled optimization: wolfCrypt Benchmark (block bytes 1048576, min 1.0 sec each) RNG 10 MiB took 1.459 seconds, 6.855 MiB/s AES-128-CBC-enc 15 MiB took 1.028 seconds, 14.592 MiB/s AES-128-CBC-dec 15 MiB took 1.006 seconds, 14.916 MiB/s AES-192-CBC-enc 15 MiB took 1.187 seconds, 12.634 MiB/s AES-192-CBC-dec 15 MiB took 1.180 seconds, 12.713 MiB/s AES-256-CBC-enc 15 MiB took 1.359 seconds, 11.037 MiB/s AES-256-CBC-dec 15 MiB took 1.352 seconds, 11.096 MiB/s AES-128-GCM-enc 10 MiB took 1.140 seconds, 8.769 MiB/s AES-128-GCM-dec 10 MiB took 1.140 seconds, 8.770 MiB/s AES-192-GCM-enc 10 MiB took 1.256 seconds, 7.963 MiB/s AES-192-GCM-dec 10 MiB took 1.261 seconds, 7.931 MiB/s AES-256-GCM-enc 10 MiB took 1.373 seconds, 7.285 MiB/s AES-256-GCM-dec 10 MiB took 1.371 seconds, 7.291 MiB/s HMAC- and SHA- functions also have significant improvements.
