Release: SFV Ninja (Simple File Verification application)

[skwire]

Name	SFV Ninja (Simple File Verification application)
Short Description	SFV (Simple File Verification) application.  It also supports MD5, SHA-1, SHA-256, SHA-384, and SHA-512 checksum files.  I wrote this several years ago for my own use but cleaned up the code for a public release.
Features	Two verifcation modes.  The first will verify all files in the list like any typical SFV application.  The second mode will only verify any newly added files.  This second mode allows you to "update" an existing SFV file without having to verify all of the files. Recursively scan a folder for SFV/MD5/SHA-1/SHA-256 files and load them all at once. Uses relative paths whenever possible when generating checksum files.
Supported OSes	Windows 7.  Probably works, but not tested, on Windows XP/Vista/8/10

this is nice.. thanks!

Screenshot looks nice - does it have decent progress bars? Does speed rock? Does it handle >2GB files? Does it support the MD5 SFV extensions?

I personally still use the freeware FlashSFV 2.0f (iirc done by the guys that did FlashFXP) - but at one point it kinda disappeared off the radar, and I haven't checked out the most recent 2.6. Might be interesting to pit it against your tool

1. The progress bar is less than desirable by your standards, I'd say.
2. Speed should be fine.  It is for me, anyway.
3. I've tested with 1GB sized files.  Now tested successfully with 4GB sized files.
4. No, only standard CRC32 SFV files.  Now supports SFV, MD5 & SHA-1 checksum files.

One of the main reasons I wrote this five years ago was that I wanted to be able to easily scan through a directory, load all the SFV files found and batch check them.  Nothing I could find back then really suited my purposes.

[skwire]

I just tested out the latest FlashSFV and, unless I'm mistaken (entirely possible), here are some of my findings:

1. It can't handle Unicode paths.
2. It can only create an SFV file out of files from one folder.
3. It does not save the SFV with relative paths.  In other words, if you save the created SFV into another folder other than the one with the checksummed files, it won't work anymore.

The above items are important to me so SFV Ninja does all three.  It handles Unicode paths just fine and writes its SFV files out in UTF-8 format.  You can also build an SFV file out of files that come from any number of folders.  The resulting SFV file is then saved with paths relative to the save folder of the SFV file.  Furthermore, I tested out SFV Ninja on a 4GB VM hard drive file and it worked just fine.  Give it a shot, you may like it.

Hello, I've just signed up after I saw your app..
I've been looking for months for this feature: Recursively scan a folder for verification files and load them all at once.
So I've to ask is it planned to add support for md5 anytime in the future?

[skwire]

So I've to ask is it planned to add support for md5 anytime in the future?

Honestly, I hadn't planned on it.    I'm going to assume that you use .MD5 files instead of .SFV?

[skwire]

BTW, Marc.D, welcome to the site. 

[Marc.D]

Well yes I've used them all the way long for my music (along with foobar ... )
I'm out of luck? duh

BTW, Marc.D, welcome to the site.   

Thanks

[skwire]

I'm out of luck?

Not necessarily.  Let me do some research and see what it will take to add MD5 support.

[skwire]

Update:  I have the application working with MD5 and SHA-1 hashes.  I just need to write the file loading and saving routines (easy stuff) and it should be done.  

I did want to get some input on how to handle the three different types of hashes.  Even though it's easy to differentiate between the different hashes due to their checksum length, I'd like to stay away from any sort of fuzzy logic stuff that would attempt guess at which type of hash is being called for.  The reason for this is that I don't want to encourage mixed hash types in the list.  Does this make sense?  So, with that being said, I was thinking three new "mode" buttons on the toolbar; one each for crc32 (SFV), md5 and sha-1 modes.  The user will need to set one of the three modes before attempting to load and/or check files.  Does this sound like a reasonable solution?  If not, feel free to suggest something else.  

[Marc.D]

It sounds reasonable to me. I actually didn't thought about it and I agree I would prefer not to check other types of hashes that may be loaded and mixed in the list.

v1.0.3 - 2011-04-08
    + Added modes/support for MD5 and SHA-1 algorithms.  (Thanks, Marc.D)

[Marc.D]

Thank you Skwire, really appreciated
It's working nice here.

[skwire]

So, I presume you were able to recursively load MD5 files from your music folder?  Also, if I may, are the changes intuitive enough?  One thing I still need to add is a way to cancel a scan (either with a button or, say, the Escape key).

[Marc.D]

IMHO I think they are ok...

One thing I still need to add is a way to cancel a scan (either with a button or, say, the Escape key).

Well yes, I thought of using the exit button in those cases ...

There seems to be an error when loading checksums recursively for a drive. I noticed that the file path has a double "\\" like "E:\\" and it returns an error when is closed. This is the report:

PD: Out of laziness could the selected checksum mode button be remembered? : D

   + Pressing the Escape key during a scan will cancel the scan.
   + Checksum mode is now saved.  (Thanks, Marc.D)


As for that error, I can reproduce it.  However, I haven't a clue why it happens. 

[Marc.D]

: O : O

+ Checksum mode is now saved.

Thanks again

Nice tool skwire.

[skwire]

Nice, thanks for the heads up.

Awesome tool, Sir Skwire

Any chance of SHA-256 support?  I came across:

 http://www.imagemagick.org/download/binaries/digest.rdf

and failed to find other checksums...

Oh...and is there some hidden feature in the Help -> Contents dialog?


P.S. No official checksums for SFVNinja itself?

[skwire]

Awesome tool, Sir Skwire

Thanks.  =]

Any chance of SHA-256 support?

Find me a free, stand-alone commandline executable that will spit out an SHA-256 checksum and, sure, I'll add it.

Oh...and is there some hidden feature in the Help -> Contents dialog?

Nope...yet another example of my laziness.  I really should put something there, eh?

P.S. No official checksums for SFVNinja itself?

Oh, the irony.

Find me a free, stand-alone commandline executable that will spit out an SHA-256 checksum and, sure, I'll add it.

I haven't tried any of these, but they may work (they're standard GNU tools):

I have compiled native (no Cygwin, no other dlls) Windows versions of md5sum.exe, sha1sum.exe, sha224sum.exe, sha256sum.exe, sha384sum.exe and sha512sum.exe. Download binaries here, and source (as required by GPL) here.

You might have to pass the `-b` option to force the programs to read in binary mode.

How does sha256deep.exe from md5deep look?
