For me, this program is a MAJOR FAILURE so far. I tried this out on an encrypted PDF file from work (they email our "check stubs" as an encrypted PDF). I know the password, so I thought this would be the perfect test. I started out with just the basic Dictionary Attack and within about 10 minutes time it claims to have found the password. "Decryption process finished. Your password has been recovered: twain cloud"

Really? OK, but WHICH password has been found? I opted for it to find BOTH the User and Owner passwords (both are set on this PDF as there is a padlock image under each column). It has given me ONE password, doesn't tell me WHICH ONE it is, (no check boxes in either of the "recovered passwords" boxes) and on top of that, it is NOT THE CORRECT PASSWORD!

I have now started a Mask Attack and I made it really easy for the program; I set it to scan the exact number of characters in the password, and only selected the character sets that are actually used in the password and set it to work. I will update later with my findings on that.

Well, it looks like it may be some time before I can give an official update. Not sure if it is my PC or what, but this thing is slow. It's an 8-character password. This thing, in about 18- hours has scanned just over 62.5 million combinations. it hasn't even decremented the 7th or 8th characters yet, and is only in the "b's" on the 6th. Will probably be close to 2 weeks or more before it reaches what should be the correct password. Will try to remember to update this once it completes.

FeMaster, Sounds like my short review. It found one of my passwords using the Mask feature and it found the User one but has not finished as of yet to find the Owner.

My PC crashed with a BSoD, so the multiple days worth of progress I had in testing the Mask Attack was for naught. I can't say if it had anything to do with this software or not, but I can say it has never happened before...

With the Dictionary attack giving false results, the inability to further customize the Mask (like starting from the bottom [zzzzzzzzzz] and work it's way up), and the incredible number of spelling and grammatical errors, I'm going to write this off as a glorified Beta Test (no way it's revision 4.0 with that many mistakes!) failure and move on with my life.

Uninstalled and not looking back...

I tried this on a file that had a simple 4 letter password using the dictionary attack mode. It incorrectly identified it and even went all the way up to 7 letters. I tried the password thinking it may have been different, but no go. Tried it on another file and same thing. Did not correctly ID the password.

The code doesn't work for the portable version. Says the no appropriate license found. The install of the regular setup file went flawlessly tho. Any help from the developers of the application or giveawayoftheday? Thank you both.

nevermind. I fixed the issue. was trying to activate it on the pc then move it to the thumb drive. you have to move it to the thumbdrive first then activate it. Just a heads up to anyone who might be trying to do it that way.

James, Where did you find a portable version? Or did you install and then copy on a USB key (fir instance) and then activated it?

James, Did'nt you want to speak rather about Silver Key Standard?

vijay, this program is written in Microsoft Visual C# / Basic .NET (PEiD scan) so check your version of .NET Framework if you have any.
z, this program no need admin privilege.

Product looks good ... considering how much time hacking passwords from anything can take it is unlikely we will be able to test this out in a real world password recovery during the giveaway period though someone might fabricate a simple password protected PDF with a known easily guessable password or two to test it within the giveaway time slot. Provisionally I am giving this a thumbs up, there is no indication that this is an expiring license at this time but I have not wound the system date forward a few years yet to confirm it.

TK, I tried this on 2 PDF files with simple name passwords, one 4 letters and one 7 letters. The password words were in the dictionary file included, so no doubt they did not exist there. On both instances, it failed to tell me the password. It did give me a "password found" and told me what it thought it was. I tried it anyway on both user/owner slots, but did not work. As of now, it is thumbs down from me. I'll try the other options, Mask/Brute, at a later time to see how they do on the easy passwords.

Andy, Same was my experience as I outlined in post #6 above. By any chance do you remember what it claimed the password was? Just curious if it picked out the same wrong password for you as it did for me. I'm currently running the Mask Attack, but the password is 8 characters, and even though I I set it up to scan only 8 character passwords and using only the character sets in the password, it looks like it may take a week or more before I have results and can verify if it actually found the password.

Andy, I tried it yesterday on a Nitro PDF printer generated PDF with a known password and considering the claims it is multi threading capable it's usage of a dual core CPU was decidedly unimpressive only using around 56% peak of CPU, I was expecting maxing out all CPU and GPU cores as password checking is easily split into several threads covering different sections of the password ranges and each run on its own CPU/GPU core producing at least hundreds of thousands of password tries per second but this was slooooooow 950 passwords PER MINUTE!! completely impractical. I knew the pass phrase was just numbers and 10 digits which is a weak passphrase but would take far too long to find this simple passphrase even if it could... Now consider adding upper and lower case letters too and it'd be quicker to re-compose the document and generate a fresh PDF without the password protection.

In additon on the GUI where the list of PDF files will apear once added if you mouse over it it shows a tool tip inviting us to drag and drop PDF file to decrypt... but when I try do drag and drop a PDF file from an explorer.exe window onto this program no matter where I drag it to on the GUI all that shows up is a black no entry cursor! Is anyone alpha testing this program in house?

TK, I'm surprised yours was that slow. I thought mine was running slow on my old quad core, averaging about 37,000 to 47,000 passwords a minute depending on load, but 950 is just ridiculous! With a 10-digit password, you'd be there for YEARS trying to crack it. Your PC would probably die before it ever found it.

I also noticed lots of grammatical errors, which can probably be attributed to poor English translation, but at the same time, under the Dictionary Attack, in the description, it is spelled "dictionray". With all the issues and errors, I really get the feeling that this isn't a version 4.0 release, but more like software that is still in the Beta Testing phase.

Can't install the software!

When I try to install the software, firstly a message tells me "Connecting to giveawayoftheday.com. checking giveaway availability. Then another message tells me "Failed to Connect". What should I do please???

Hassan, check the setting of your firewall. The installer must be allowed to connect to the internet.

Reply   |   Comment by Cereus  –  Last month  –  Did you find this comment useful? yes | no (+4)

Hassan,
If the problem isn't with firewall, make sure that your date and time of the PC is correct and then try again.
