Here is minimal source-only "git archive" sources:

Here are the SHA256 and SHA3-256 checksums:

  File: wdiff-1.2.3.tar.gz
  SHA256 sum:   29a4457eb0ed35c902e6732d71f25e1d6c7fe7fa0eda0fb6c371ed6779b49fd6
  SHA3-256 sum: 2f558fe6b7a69524f29d266c4018c80a10135cef2e4a53ae3c2944c1fc12c95d

  File: wdiff-v1.2.3-src.tar.gz
  SHA256 sum:   dc29d8f530471b9a8935413dca32e45848363f6e58888fc7307f5f052b8fb827
  SHA3-256 sum: 4db1f41eda5e1525f3ced491af1fc1ad094cc21c209e789d12a1ea8f611be24e

Verify the SHA256 checksum with either sha256sum, sha256, or
'shasum -a 256'.

Verify the SHA3-256 checksum with 'cksum -a sha3 -l 256 --base64'
from coreutils-9.8.

Use a .sig file to verify that the corresponding file (without the
.sig suffix) is intact.  First, be sure to download both the .sig file
and the corresponding tarball.  Then, run a command like this:

  gpg --verify wdiff-1.2.3.tar.gz.sig

The signature should match the fingerprint of the following key:

  pub   ed25519 2019-03-20 [SC]
        B1D2 BD13 75BE CB78 4CF4  F8C4 D73C F638 C53C 06BE
  uid   Simon Josefsson <[email protected]>

If that command fails because you don't have the required public key,
or that public key has expired, try the following commands to retrieve
or refresh it, and then rerun the 'gpg --verify' command.

  gpg --locate-external-key [email protected]

  gpg --recv-keys 51722B08FE4745A2

  wget -q -O- 'https://savannah.gnu.org/project/release-gpgkeys.php?group=wdiff&download=1' | gpg --import -

As a last resort to find the key, you can try the official GNU
keyring:

  wget -q https://ftp.gnu.org/gnu/gnu-keyring.gpg
  gpg --keyring gnu-keyring.gpg --verify wdiff-1.2.3.tar.gz.sig
