The original benchmark commit was 
https://github.com/weidai11/cryptopp/commit/ce38a411fc5324a2 in March 8, 
2017.

SHA-256 was added to Hash_DRBG and HAMC_DRBG at 
https://github.com/weidai11/cryptopp/commit/ef7a6a2f4e1ad29d on March 11, 
2017.

You should probably perform a 'git pull' and then rebuild.

Thanks Jeff for your answer.
I run the Benchmark test(cryptest.exe b 3 2.0 > benchmark.html). I had just 
1 variant result :



 

So I add those lines, in bench1.cpp file, to have all the statistics, but I 
have an exception message: “ CryptoPP::Exception caught: 
ObjectFactoryRegistry: could not find factory for algorithm HMAC(SHA265)” :

If you have a Goldmont microarchitecture with the SHA extensions, then 
SHA-1 will run at about 3 cycles per byte; and SHA-256 will run around 4 or 
5 cycles per byte.

HMAC Benchmark

[Abderrahim HAJJI SOUALFI]

Hi

I want to know a benchmark comparison of the HMAC(*keyed-hash message 
authentication code*) variants: HMAC-SHA-1, HMAC-SHA-224, HMAC-SHA-256, 
HMAC-SHA-384 and HMAC-SHA-512.

I will use it in ad hoc case, and I want choose the right one!

Thanks in advance.
