====================================================================
Details & Usage
====================================================================
Built on .NET Framework 4.5

Supported Checksum Algorithms:
MD5, MD5-CNG
SHA-1, SHA-1 Managed, SHA-1 CNG
SHA-256, SHA-256 Managed, SHA-256 CNG
SHA-384, SHA-384 Managed, SHA-384 CNG
SHA-512, SHA-512 Managed, SHA-512 CNG
RIPEMD160, RIPEMD160 Managed
CRC16
CRC32

Supports 3 modes:
Single File
Multiple File
Text string

You can generate hashes for either mode, or compare to a checksum provided to the program by the user.

To use (single or Multiple File modes):
1) Select desired algorithm(s) (default is MD5 - assumed this would be most used)
2) Select a tab (mode) to use
3) (Optional) If verifying a file's checksum, enter it in the "Checksum" field.
4) Browse for a file to generate
5) Click the Compare button
Note: for large files it may take some time... be patient!
6) The result will appear in the appropriate section in the tab's section.
a) For Single File mode: the checksum generated for the file will appear in the "File Checksum" field. If comparing to an entered Checksum, the result will display below the File Checksum field, noting if it is a match or mismatch. The checksum generated from the file will also turn green for a match, and red for a mismatch.

b) For Multiple Files mode: The generated checksum(s) will appear in the list to the right of the Browse and Compare buttons for each file. It will also note if there was a match or mismatch to the given Checksum (if one was given).

To use Text String Mode:
1) Select desired algorithm(s)
2) Input a text string in the "Input String" box
a) Input a checksum to compare against if desired
3) Select an encoding method
4) Click Generate/Compare button

Updated attachment to v2.5.1

 

[carnageX]

Updated to Version 2.5.3 - most notable change is adding CRC16 support.

Cool, I didn't know what checksum was until I googled it. May be useful!

Not bad. Some suggestions for future additions:
1. Ability to resize the window, because this:

2. If not 1, then the ability to output a text file with the filename(s) and computed checksums for that file or batch of files
3. Hashing in more than one algorithm at once; often we do MD5+SHA1 concurrently in forensics (technically unnecessary but desired in courts)
4. Either a "Copy" button that puts the hash into the clipboard, or automatically doing so when a user clicks on the has

1. Can do - I was just too lazy to modify the controls to be expandable or static .
2. Didn't think of that, I like that idea. Easily implemented as well.
3. So you mean do: compute hash of MD5, then hash of SHA1? Or is there a different algorithm for MD5+SHA1?
4. I believe I set it so you can right-click in the computed panel, and copy 1 or all.

Thanks for the suggestions .

First one, then the other.

 

[carnageX]

First one, then the other.

So it'll just show both checksums side-by-side, essentially?

Yup Ideally, it'd do that and the output would be something like

filename.ext[tabspace]MD5[tabspace]SHA1

At least in the case of hashing multiple files at once.

Updated to Version 2.6.0
* Allow form to be resizable / maximized
* Changed display format of Multifile results
* Allow export of Multifile results to a text file

Still looking into the best way to do multiple algorithms.
