Awesome
C port of the BLAKE3 Rust reference implementation
Run test.py
to build and test the blake3
binary. The binary
hashes stdin and prints the result to stdout. You can run it like this:
$ ./test.py
[build and test output...]
$ echo hello world | ./blake3

$ echo hello world | ./blake3 --len 100

$ echo hello world | ./blake3 --key 0000000000000000000000000000000000000000000000000000000000000000

Note that putting --key
on the command line as in the example above isn't
something you should do in production, because other processes on your machine
can see your command line arguments. This binary is for demo and testing
purposes only and isn't intended for production use.
This implementation tries to be as simple as possible, and the only performance
optimization here is liberal use of the inline
keyword. Performance isn't
terrible though, and under clang -O3
this is a hair faster than Coreutils
sha512sum
on my laptop.
