21.04 beta 2021-11-02
- 7-Zip now reduces the number of working CPU threads for compression,
if RAM size is not enough for compression with big LZMA2 dictionary. - 7-Zip now can create and check "file.sha256" text files that contain the list
of file names and SHA-256 checksums in format compatible with sha256sum program.
7-Zip can work with such checksum files as with archives,
but these files don't contain real file data.
The context menu commands to create and test "sha256" files:
7-Zip / CRC SHA / SHA-256 -> file.sha256
7-Zip / CRC SHA / Test Archive : Checksum
The commands for command line version:
7z a -thash file.sha256 *.txt
7z t -thash file.sha256
7z t -thash -shd. file.sha256
New -shd{dir_path} switch to set the directory that is used to check files
referenced by "file.sha256" file for "Test" operation.
If -shd{dir_path} is not specified, 7-Zip uses the directory where "file.sha256" is stored. - New -xtd switch to exclude directory items from processing.
