CRCDropper

#1 Post by smaragdus » Sun Nov 27, 2016 10:53 pm

Synopsis
CRCDropper is a simple and tiny (only 84 KB compressed) checksum calculator.

Features
  • CRCDropper supports 10 hashing algorithms (in alphabetical order- CRC16, CRC32, MD2, MD4, MD5, RIPEMD160, SHA1, SHA256, SHA384, SHA512).
  • CRCDropper supports drag&drop of both files and folders (if a folders contains sub-folders, the contents of the sub-folders will also be processed).
  • CRCDropper can also be started up from the command-line.
  • CRCDropper supports Unicode.
  • CRCDropper program window can be resized.
Command-line
CRCDropper can also be started up from the command line, and supports these
options:

Code: Select all

 -crc32 <filename> ...	(default if no option given)
 -md2 <filename> ...
 -md4 <filename> ...
 -md5 <filename> ...
 -sha1 <filename> ...
 -sha256 <filename> ...
 -sha384 <filename> ...
 -sha512 <filename> ...
 -crc16 <filename> ...
 -ripemd160 <filename> ...
Example:
C:\> crcdropper3.exe -md5 test1.dat test2.dat -md4 test1.dat test2.dat

This will calculate MD5 hash for the files test1.dat and test2.dat, then the
MD4 hash for the same files.

Portability
CRCDropper version 3.4 is portable and stealth by design- it does not save any settings.

Requirements
CRCDropper has no special requirements.

License
CRCDropper is freeware.

Note
I contacted the developer with several suggestions and he was kind to respond and promise to implement at least some of them.

I definitely like the size and the simplicity but two key features compared to similar toolsets include:

- No batch verification
- Lack of output/report (e.g. create .sfv or .md5 files)

Still a cool program.

Some good news, the developer of CRCDropper sent me a test version which is much better (I hope I am not revealing a secret):
So far I have added in the "Stay on top" option and saving/loading the window size and selected hash to/from a .conf file in the same folder as CRCDropper. In fact the .conf file gets its name from the .exe file, so you can have multiple copies in the same folder with different options by naming the CRCDropper.exe file to something different.
I think that having executables with different settings in the same folder is very cool.

The new "Stay on top" option:

CRCDropper at version 3.5 (file version- 3.5.0.3), changes:
01/2017 3.5
Added "Stay on top" and "Lower case" checkboxes, saving options to crcdropper3.conf file. Added support for multiple selection, context menu and export options.
Context menu for single file selected:

Context menu for multiple files selected:

To celebrate this significantly improved new version of CRCDropper (settings saved to program folder, program remembers window size and position and last used hashing algorithm, hashes in lower/UPPER case, Stay on top, context menu, export hashes to single file or to separate files) I added CRCDropper to the database.

In testing a few of the minimal file hashers, I found that CRCDropper3 would be more convenient if the export options were available through the CLI parameters. Also, the export format could be made more multi-platform friendly if it followed the 'hash filename' format.
