makeself VS BLAKE3

Why not try a self-extracting archive?

see https://makeself.io

Thanks for introducing Zerobrane, really looks fantastic. Also by extension introduced me to https://makeself.io/ for making Linux installations.

Yeah, I can understand that, but the same advantage doesn't easily apply to situations like Rust, where you're already quite unlikely to be building the program on your production machines. I've done the same for Python many times, actually, using pip download to retrieve dependencies and building a package that is then installed on the target machine with some makeself mess. It actually worked surprisingly well, much of the time.

edit: you might wanna check out makeself

> might be easier with a public domain license instead of the current ones

There reference implementation is public domain (CC0) or at your choice Apache 2.0

Fyi, blake3 was released in 2019 and should probably be used over blake2 unless you have some strong reason not to. It's basically a reimplementation of blake2 with performance tweaks.

Many people will argue that today's compilers are so smart/optimized that you'd be a fool to try to outsmart the compiler with asm. I'm not 1 of them, but I know some. IMO it's all a bunch of bullshit, there's a goddamn reason all the cryptocurrency mining CPU/GPU code is all hand-written asm. there's a reason blake3 is written in asm ( https://github.com/BLAKE3-team/BLAKE3/blob/master/c/blake3_sse41_x86-64_windows_msvc.asm ) - but the thing is, 99.99% of the time, life is too short to outsmart the compiler (unless you're Alexander Yee)

I have been trying to optimize my code to create a fast hashing function to create and check b3 file integrity but b3sum is way way faster than my aproach, i have been trying to modify my code acordingly to https://github.com/BLAKE3-team/BLAKE3/blob/master/b3sum/src/main.rs with no luck, so if anyone can give me some tips/clues on how to achieve better speeds it would be incredible. Thx!!

BLAKE3 might be faster than KangarooTwelve and is also an XOF. It doesn't have the benefit of getting a working RFC draft proposal however.

You're saying the hash speed is 133 kB/s? That's extremely slow, for example BLAKE3 achieves 6.8 GB/s which is over 50000 times faster. Nobody wants to use such a slow hash function.

Try this one if you want a smaller, and particularly interesting crate: https://github.com/BLAKE3-team/BLAKE3

blake3 is a cryptographic hashing function, which is used during plotting's "forward propagation" step

BLAKE3 claims to be faster and more secure than both MD5 and SHA1.
