Blake3 using the official BLAKE3 c implementation.
- Fast. ~2x faster than Sodium::Digest::Blake2b.
- Uses Crystal's Digest API.
- Keyed digests.
- Key derivation.
- Configurable final size.
- Streaming final output.
- Tested against official test vectors.
- Builds a blake3 c static library.
examples/blake3_hash.cr is approximately the same speed as b3sum with 1 thread or mmap disabled.
-
Add the dependency to your
shard.yml
:dependencies: blake3: github: GeopJr/blake3.cr
-
Run
shards install
require "blake3"
digest = Digest::Blake3.new
digest.update data
p digest.final.hexstring
output_size = 1024
digest = Digest::Blake3.new(output_size)
digest.update data
p digest.final.hexstring => ...a.very.long.string...
digest = Digest::Blake3.new(key: "super secret exactly 32 byte key")
digest.update data
p digest.final.hexstring
