---------------------------------
Summary: Add support for Blake3 family of hashes
Key: CODEC-296
URL: https://issues.apache.org/jira/browse/CODEC-296
Project: Commons Codec
Issue Type: New Feature
Reporter: Matt Sicker
Assignee: Matt Sicker
Brief historical context: the original Blake hash algorithm was a finalist in
the SHA-3 competition. The second version, [Blake2|https://www.blake2.net/],
has several variants, the most popular seem to be Blake2b and Blake2s, though
there are a few others that are tuned and tweaked for different use cases. This
brings us to [Blake3|https://github.com/BLAKE3-team/BLAKE3], the third version
of the hash algorithm which unifies the variants into a single interface along
with further tuned security parameters for increased performance with
negligible impact on security.
Blake3 is extremely versatile and offers interfaces to use it as a message
digest (hash) function, pseudorandom function (PRF), a message authentication
code (MAC), a key derivation function (KDF), and an extensible output function
(XOF). It is also faster than MD5 and SHA-1 (and SHA-2 and SHA-3) while
remaining secure which makes it handy for less security-intensive contexts,
too, like file hashing.
I've previously ported the reference public domain Rust implementation to Java
for another use case, so the algorithm itself is pretty simple to add here.
This library doesn't define any interfaces for these concerns, though the Java
crypto API does have some equivalents for most of those use cases, but they
might be overkill for this.
