 ## Task Completed
 
-This technology test has been done in my MuPDF-based toolchain. One notablee difference is the use of BLAKE3 instead of SHA256 as the new hash algorithm as that onee is *faster*, both theoretically and in practice, while offering the same quality of uniqueness guarantees.

 The new `mutool qiqqa_fingerprint0` and `mutool qiqqa_fingerprint1` tools calculate the classic Qiqqa hash and the new BLAKE3+Base58 hash, respectively.
