%description
BLAKE3 is a cryptographic hash function with features like Extendable
Output Function (XOF), Key Derivation Functions (KDF), Pseudorandom
Functions (PRF) and Keyed Hashes (MAC). It introduces a Merkle tree
structure that enables parallel computation across multiple cores.
BLAKE3 offers a fixed 256-bit output and targets memory efficiency.

%package -n b3sum
Summary:        A command line utility for calculating BLAKE3 hashes

%description -n b3sum
A command line utility for calculating BLAKE3 hashes, similar to
Coreutils tools like b2sum or md5sum.
