A .sha256 file is a plain text file that users can optionally download to verify the integrity of a plugin. It contains a SHA256 checksum, which is a cryptographic hash value generated from the plugin's contents. Users can compare the checksum of the downloaded plugin with the checksum in the .sha256 file to determine if the plugin's contents have been altered or corrupted during the download process. If the checksums match, the plugin is verified as intact and authentic. If they do not match, it indicates possible corruption or tampering.
