    any chance of adding the ED2K (edonkey/emule) HASH
    like HashCalc has, ive found this usefull

    Nice one, as fast as hashtab.
    Good job!

    Thanks for that helpful app but i experience problems when using the Drag&Drop
    feature in v0.9. No clue what`s wrong with it. o_O

    edit:

    v0.8 works fine for me

    v0.9 works now, too but from a different source. Maybe datafilehost hates me.:D

    Thanks, great program.

    Does it have the functionality to hash strings? Would be good for testing cryptographic code I write IN PHP etc. then

    Nice App!
    Currently I am using Hashtab to display and compare hashes, but this app has many other useful functions, such as read/create SFV and MD5 files, hash text...
    thanks! :aerobueke:

    Also, as for the MD5 is considered unsecure bit, that's not strictly true. It can be bruteforced with relative ease due to the fact that it's optimized to compute very quickly but a cryptographic hash by nature cannot be forged in the sense that it can produce the same hash without the same data, apart from a few, select contexts (collision attacks, which are impossible to create in a legitimate piece of binary data)

    How does the speed optimatization work then? To get it faster and create vulnerabilities at the same time, the only thing I can think of is skipping parts of the file, but how does it work exactly?

    they are written to generate a hash very quickly so as to identify large files uniquely etc., however some hashes are desired for their slowness to compute, for instnace, if a hash is difficult to compute, it cannot be bruteforced and therefore reversed very easily, so difficult hashes are often used for crypting sensetive ata like passwords, whereas quick hashes are often used for uniquely identifying files etc. where a collision attack can only be prouced by uniquely crafted data which wouldn't apply to file comparisons.

    I generated (and exported to file) hashfiles for 2 ISO's but only the later one was saved to hash.txt

    Seems the app overwrites the hash.txt with the later calculated checksums instead of just adding, a fix perhaps?

    It's probably a bit dirty, but read all the lines of the file to a string array, add the new hashes also to the string array, then write the string array to the file.

    That does need updating, depletes itself after each hash saved..
    Ill fix it in next release..
