This is the updated version of the Merkletree code, version 20220204

Digests supported are a bit more up to date:

blake2b
blake2s
sha256
sha3_256
sha3_512
sha512

The default algorithm is sha512, with an input blocksize of 1024.
Input can either be in the form of files, other directory entries, or
from standard input.

Output is in either standard format (similar to digest(1)),

% merkletree 1.in
sha512/1024 (1.in) 902387724175187f42a6bce7ab7f1a88a4ce536662880747347dc5ea761fed5a7dac5e98962c60b5c3d7988258c0c9e2a14e37cfeb7972fe9086e693381324c8
% merkletree < 1.in
902387724175187f42a6bce7ab7f1a88a4ce536662880747347dc5ea761fed5a7dac5e98962c60b5c3d7988258c0c9e2a14e37cfeb7972fe9086e693381324c8
%

or can be in JSON format:

{"name":"1.in","blocksize":1024,"digest":"sha512","1:0":"902387724175187f42a6bce7ab7f1a88a4ce536662880747347dc5ea761fed5a7dac5e98962c60b5c3d7988258c0c9e2a14e37cfeb7972fe9086e693381324c8"}

(or, run through jq):

% jq . < dist/tests/11.expected
{
  "name": "1.in",
  "blocksize": 1024,
  "digest": "sha512",
  "1:0": "902387724175187f42a6bce7ab7f1a88a4ce536662880747347dc5ea761fed5a7dac5e98962c60b5c3d7988258c0c9e2a14e37cfeb7972fe9086e693381324c8"
}
%

The input blocksize can be specified by the user, but must be twice
the size of the selected digest's algorithm in raw bytes.

It is possible to run merkletree on a hierarchy by using the "-p path"
argument:

% merkletree -a sha3_256 -p / bin
