BLAKE3

Trying out the BLAKE3 cryptographic hash function ( HN discussion ).

Let's first install it via cargo . 

cargo install b3sum

154.8s

BLAKE3 (Bash)

Rust

Then we're generating a 1GB file.

head -c 1000000000 /dev/urandom > /tmp/bigfile

8.2s

BLAKE3 (Bash)

Rust

Hashing it with SHA-2 takes ~7 seconds.

time shasum -a 256 /tmp/bigfile

7.7s

BLAKE3 (Bash)

Rust

With blake3 only ~0.8s.

time b3sum /tmp/bigfile

1.4s

BLAKE3 (Bash)

Rust
