Once you forgot PDF password, the data in the encrypted PDF
file are on the risk of unavailability. Unless fortunately the password
knocks your memory again, you got the data lost or you have to give up
the document eventually. With the ever-growing of strong encryption
algorithms, decryption algorithms gradually come into existing, too.
Though the cracking is far more difficulty than ever before, it is
still of help to those expecting to recover PDF password and access the password protected PDF file. Take PDF Password Unlocker, a popular PDF password recovery software, for example, it has adopted the advanced decryption algorithms to crack 40-bit RC4, 128-bit RC4, 128-bit AES, and 256-bit AES encrypted passwords with 3 attack methods, Dictionary attack, Brute-force attack, and Brute-force with Mask attack
For security, we often protect our PDF file by password , such as some academic papers or network magazines. If we want to edit secured PDF, we would better unlock them first. But something bad often happen, For example, when we want to print a secured PDF file, but the password is lost; or if we want to extract some excellent pages from a PDF file, we would fail to copy them. So how to unlock and edit secured PDF? Fortunately, as far as I know, there are methods, such as Brute Force Attack and Dictionary Attack can resolve the problem. However another question comes, with so much software can retrieve PDF password, which one should be chosen? Well, according to my own experience, I recommend you PDF Password Recovery 5.0 an easy-to-use tool designed for removing passwords added to Adobe Acrobat PDF documents.
Features: 1. All versions through Adobe Acrobat 9.0 are supported 2. Do NOT need Adobe Acrobat software. 3. Easy to use: step-to-step guide and screenshots 4. Recovers user password required to open the file 5. Decrypts PDF files protected with owner passwords 6. Instantly removes restrictions on copying, printing and other actions with the file 7. Program automatically saves password search state and can resume after a stop or a crash 8. Patterns can be used to minimize search time if any part of the password is known 9. Passwords of any length and complexity can be recovered 10.Free updates during one year. you can download the product form Password Recovery Official site http://www.recoverlostpassword.com/
If you are using a windows driver do not use Topix in the graphics.
Use 8 bits or 4 bits. The firmaware may not be able to understand the Topix algorithm. What you have is a syntax error displayed.
That posses a problem. They know there is a problem with the algorithm but don't plan to fix it. Wonderful. The problem is this, you would have to know what the algorithm was to be able to do anything about it and I doubt very seriously they are going to release that. That leaves you with the option of hiring a hacker to break the code or paying a specialty company to break the code and they are not cheap or well advertised. I can't think of any companies that do that work anymore. You are going to have to identify a Security company or the company that originally developed the Algorithm and see if you can work out a deal to get the corrected algorithm. The problem you have is your algorithm was designed for files smaller than 4gb and there is a permutation error that occurs on files that are larger. In a lot of cases this is a random fault that makes it very difficult to identify if not impossible depending on what level of encryption the algorithm actually represents. 32 or 64 bit encryption isn't so bad but 128 or higher is a real pain and expensive. There are some software packages available out there if you search the web for them, "Decryption Software", but again it is expensive and hard to find.

Here are the diffenent types of Security Settings possible with a wireless router: (how to set this depends on the brand of router)
Security Mode: You may choose from Disable, WEP, WPA-Personal, WPA2-Personal, WPA-Enterprise, WPA2-Enterprise, or RADIUS. All devices on your network must use the same security mode in order to communicate.
Capture(wlansec.wpapersharekey)
WPA Personal:
Capture(helpwpa.phase8)
WPA Algorithm: You may choose from TKIP or AES.
Capture(helpwpa.phase9)
WPA Pre-Shared Key: Choose a unique key to authenticate with other devices on your network. The Pre-Shared Key must be between 8 and 63 characters in length.
Capture(helpwpa.phase10)
Group Key Renewal: This settings determines how often your group key changes.
Capture(wlansec.wpa2persharekey)
WPA2 Personal:
Capture(helpwpa.phase11)
WPA2 Algorithm: You may choose from AES or TKIP+AES. Choose TKIP+AES if you have both WPA and WPA2 devices on your network.
Capture(helpwpa.phase12)
WPA2 Pre-Shared Key: Choose a unique key to authenticate with other devices on your network. The Pre-Shared Key must be between 8 and 63 characters in length.
Capture(helpwpa.phase13)
Group Key Renewal: This settings determines how often your group key changes.
Capture(wlansec.wparadius)
WPA Enterprise:
Capture(helpwpa.phase14)
WPA Algorithm: You may choose from TKIP or AES.
Capture(helpwpa.phase15)
RADIUS Server Address: The IP address of your RADIUS server.
Capture(helpwpa.phase16)
RADIUS Server Port: The port your RADIUS server uses.
Capture(helpwpa.phase17)
Shared Secret: The shared secret set on your RADIUS server.
Capture(helpwpa.phase18)
Key Renewal Timeout: Determines how often your keys should be renewed.
Capture(wlansec.wpa2radius)
WPA2 Enterprise:
Capture(helpwpa.phase19)
WPA2 Algorithm: You may choose from AES or TKIP+AES. Choose TKIP+AES if you have both WPA and WPA2 devices on your network.
Capture(helpwpa.phase20)
RADIUS Server Address: The IP address of your RADIUS server.
Capture(helpwpa.phase21)
RADIUS Server Port: The port your RADIUS server uses.
Capture(helpwpa.phase22)
Shared Secret: The shared secret set on your RADIUS server.
Capture(helpwpa.phase23)
Key Renewal Timeout: Determines how often your keys should be renewed.
Capture(wlansec.wep)
WEP:
Capture(helpwpa.phase24)
Default Transmit Key: The key you would like to use for transmitting WEP keys.
Capture(helpwpa.phase25)
WEP Key Bit: You may select from 64-Bit or 128-Bit encryption.
Capture(helpwpa.phase26)
Passphrase: You may enter a passphrase consisting of any keyboard character to be used to generate a hex WEP key. Passphrase option is only supported when you are only using Linksys devices on your network.
Capture(helpwpa.phase27)
Key 1-4: You may enter a WEP key manually. You must use only hex characters (0-9 and A-F). 64-Bit WEP requires 10 hex characters. 128-Bit WEP requires the use of 26 hex characters.
