Not researched in depth but: B2sum provided by coreutils is quite satisfacting*, it's pretty fast, while sha-3 is deemed to be slower than sha-2, maybe this could be weighted while choosing the algorithm wanted. Both seem to take advantage of modern multicore CPUs but sha-3 does 11.7 [cpb]#0 (see #1) while an email seen on the internet say blake2 can reach 1 [cpb] (see #2) #0 cpb = cpu cycles per byte #1 https://en.wikipedia.org/wiki/SHA-3#Speed #2 http://www.metzdowd.com/pipermail/cryptography/2016-May/029297.html * (in my limited experience)
