Password Cracking with 8x Nvidia GTX 1080 Ti GPUs

I have not looked deeply at mmhash3 (I guess it means murmurhash3), but wikipedia says:

[...] When using 128-bits, the x86 and x64 versions do not produce the same values [...]

which will make it unsuitable for cross-platform applications. I was talking about a usecase where you could also choose CRC32 from a security standpoint but want more collision resistance. How does blake2 performance compare to MD5?

The wikipedia page might be a bit misleading - there's a 128-bit murmur3 that uses 32-bit math (works well on most every processor), and a 128-bit murmur3 that uses 64-bit math (much faster on 64-bit processors, much slower on 32-bit ones)

ah, so there is mm3-128-32 and mm3-128-64

that makes it actually a viable alternative to MD5
