#77584 — How To Remove Password From Rar File Without Any Software

I know the password to the RAR file as I locked it myself. Is there a way to do this in WinRAR or an equivalent program? The only thing I knew to do was to extract it, then create a new RAR without the password.

Out of the box, no, you can not. Version 3 of the RAR file format (implemented first in WinRAR 2.9) encrypts the actual data itself, as well as the file headers (if requested) using AES-128 encryption. With just WinRAR, it is impossible to simply "remove" the password from an archive, since the data itself is encrypted with the password.


Given the number of open-source tools that support password-protected RAR files (e.g. unar), one could learn how to do this by reading existing source code, and then using the decrypted, but still compressed, bitstream to generate a new RAR archive. However, this is far from a trivial task, as you would then have to rebuild the RAR header manually as well (or at least ensure the file format's compatibility).


I have some heavily compressed archives and want to avoid having to extract and rezip each of those archives. The decompressing and recompressing would take a lot of time and I simply need the passwords removed (which I know) before I pass them on.


I am the sole person using my system with 12.04.

Every time I issue a sudo command; the system asks for the user password (which is good in its own way). 

However I was thinking; without activating the root account; how can I execute the sudo commands which will not ask for user password to authenticate.


NOTE: I want to execute sudo command without authenticating via password; only when they are executed via terminal.

I don't want to remove this extra layer of security from other functions such a while using 'Ubuntu software center' or executing a bash script by drag-drop something.sh file to the terminal.


(vi!) hit Escape to return to command mode. Now, if you're happy with your editing, type in :w Enter to write the file and :q Enter to exit vi. If you made a mistake, perhaps the easiest way is to redo from start, to exit without saving (hit Escape to enter the command mode) and then type :q! Enter.






Chrome on Ubuntu always asks for password for keyring. There are many posts out there suggesting ways to remove the prompt by setting up a keyring. However, I also found that when I am prompt for a password, I can press cancel and chrome still runs normally. I feel uncomfortable to surrender my password if Chrome actually doesn't need it.


Chrome is asking for the password to the keyring so it can access stored information in the keyring. You can view the keyring on your system by running the command seahorse from a terminal window. You can also just bypass the asking by closing the window and still get to your sites without a problem. Some of the security may not load properly.


Colin Pickard has an excellent answer, but there is one 'watch out' with this. There are instances (I haven't figured out the cause yet) where the total length of the "CMG=........GC=...." entry in the file is different from one excel file to the next. In some cases, this entry will be 137 bytes, and in others it will be 143 bytes. The 137 byte length is the odd one, and if this happens when you create your file with the '1234' password, just create another file, and it should jump to the 143 byte length.


Colin Pickard is mostly correct, but don't confuse the "password to open" protection for the entire file with the VBA password protection, which is completely different from the former and is the same for Office 2003 and 2007 (for Office 2007, rename the file to .zip and look for the vbaProject.bin inside the zip). And that technically the correct way to edit the file is to use a OLE compound document viewer like CFX to open up the correct stream. Of course, if you are just replacing bytes, the plain old binary editor may work.


However, if you just need access to the code, you can use a tool like oledump.py to extract the Macro code. This is useful for malware analysis, as well as getting most of the code from the file so that you don't have to start from scratch if you forget the password.


In general, how can I remove the password requirement for any role? I am not asking how to change the password but rather how to remove the password requirement (null passwd column in table pg_shadow).


Once using psql to connect via unix-socket the first line in pg_hba.conf works and (super-) user postgres may set his password to null or any string and still connect without beeing asked for password.


I received a secured pdf file, but I need to edit it and mail it. Is it possible to remove the password of a pdf file on Mac? You know I can't ask for the right password. Any help would be appreciated. Thanks.


Yep, this works for me, no special tools required, so long as you already know the password and you just want to remove the protection from the PDF file. With OS X 10.10.1, I used Preview's File->Export as PDF... menu command to save the unprotected version.


If you have the password and just want to save it as an unlocked .pdf, just open the password protected file (with the password) in Preview, choose Save, and change the name (don't select encrypt). The new .pdf file created should open without a password.




 Switch from your notes password to your iPhone passcode Make sure that iCloud Keychain is on. To use your device passcode for locked notes, you must turn on iCloud Keychain.In the Settings app, tap Notes.Tap Password.Select Use Device Passcode.Use Face ID or Touch ID, or enter your previous notes password.Enter your iPhone passcode.Tap OK. All your locked notes that used your most recent notes password are now updated to use your device passcode.If you choose to use your device passcode to lock notes but later remove your passcode from the device, you can still access the notes you locked with your passcode.


Unfortunately for the safety of your own files you cannot get into the drive again without the password to access the files. One would need to wipe the drive completely for it to be useable again. This is for the best. Certainly you would not want anybody to be able to get their hands on your data by resetting such a password without your permission.


Mathematical data can be represented in various ways, including mathematical computations, maps, infographics, and statistics. Excel also protects spreadsheets, so the benefits are far from done. Anyone who wishes to secure their material may simply secure the document using a password. The password prevents unauthorized access to that information, and it can only be opened by those who know the password.


Step 5. The General Options dialogue box appears, displaying the usernames and passwords for opening and editing the Excel document. Click "OK" after removing the credentials from both text areas.

While removing the password from MS Excel files, data loss or file corruption is a considerable risk. Just suppose you are applying different methods to remove the password, and suddenly the file goes corrupt. It could be a hectic situation if your file has some critical data.


It is always good to protect your Excel files with a password. However, it can become a hassle sometimes if you forget the password of an important file. We discussed some of the easiest ways to recover and remove Excel passwords in such scenarios.

Starting with FortiOS 7.2.4 the "maintainer" account was removed, meaning this method to reset a password will no longer work.

"Remove the maintainer account (which allowed users to log in through the console after a hard reboot). Users who lose their password must have physical access to the FortiGate and perform a TFTP restore of the firmware in order to regain access to the FortiGate."




Procedure:



Step 1.



Connect the computer to the firewall via the Console port on the back of the unit.

In most units, this is done either by a Serial cable or an RJ-45 to Serial cable. There are some units that use a USB cable and FortiExplorer to connect to the console port.



Resetting a lost admin password for the VM-s using the maintainer account is not possible. 

In this case, reverting to a snapshot or re-provisioning the VM and restoring the configuration (without a password for the admin account) is the only solution.



Step 2.



Start the terminal software.



Step 3.



Connect to the firewall using the following:
