A small program that recursively checksums files in a given directory. Can work with any algorithm provided by Java. Compiled in a format used by the GNU Coreutils checksum digests for checking.
A progress bar is shown for every file, so big files don't look as if the program hung.
Use -h or --help to see basic usage and -V or --version to check the version.

Calculating checksums for all files within the Documents directory and subdirectories and outputting the list to the Checksums folder with verbose console printing and using the SHA-1 algorithm:
java -jar path_checksum.jar -p ~/Documents -a sha1 -e ~/Checksums -v
Checking the saved list against the current files:
java -jar path_checksum.jar -p ~/Checksums/Documents.sha1 -a sha1
Can also work on big files:
java -jar path_checksum.jar -p ~/Downloads/archive.7z -a sha-512 -v -e ~/Downloads/archive.7z.sum

ProgressBar/ProgressBarBuilderhas trouble properly displaying sizes larger than 2047 MB (just shy of 2 GB), so it just displays either that or 1 GB. Appears to be an issue with using theProgressBar.wrap(InputStream, ProgressBarBuilder)factory, may have to take it with them.
- Option to use purely ASCII progress bars, in case the user's terminal doesn't support ANSI.
- Option to disable progress bars altogether, where undesired or don't work properly.
- An
--excludeparameter to exclude certain files or directories so the user doesn't have to do more manual work.
