Re: Remove Rar Password With Hex Editor
Kirby Apodaca
i have done a practice layout design in the past and i tried to lock it with a password.
now, i would like to edit the layout and perform some modifications.
is there a way that i could remove the password from my layout file so i could edit it?
is there a workaround to save the BRD file so it could be edited?
Hi,
this is an answer that was given before so I am repeating it to best of my memory.
And sorry I can not remember name of person who gave this solution.
Here it goes, take a board file and lock it with a password then open this file with text editor and
search for password and mark the place or phrase next to your given password.
Now open the file you have forgotten password for go to that specific phrase or line and see what is password is.
Hi
This is from the Cadence Help on locking:
Caution: It is extremely important that you keep a record of any passwords used to lock databases. Cadence does not support the recovery of databases in a locked state due to forgotten passwords.

Yes there is, as long as you are using a .xls format spreadsheet (the default for Excel up to 2003). For Excel 2007 onwards, the default is .xlsx, which is a fairly secure format, and this method will not work.
DISCLAIMER This worked for me and I have documented it here in the hope it will help someone out. I have not fully tested it. Please be sure to save all open files before proceeding with this option.
*NOTE: Be sure that you have changed the password to a new value, otherwise the next time you open the spreadsheet Excel will report errors (Unexpected Error), then when you access the list of VBA modules you will now see the names of the source modules but receive another error when trying to open forms/code/etc. To remedy this, go back to the VBA Project Properties and set the password to a new value. Save and re-open the Excel document and you should be good to go!
With my turn, this is built upon kaybee99's excellent answer which is built upon Đức Thanh Nguyễn's fantastic answer to allow this method to work with both 32/64 bit versions of Office.
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.
This is not valid for Excel 2007/2010 files. The standard .xlsx file format is actually a .zip file containing numerous sub-folders with the formatting, layout, content, etc, stored as xml data. For an unprotected Excel 2007 file, you can just change the .xlsx extension to .zip, then open the zip file and look through all the xml data. It's very straightforward.
However, when you password protect an Excel 2007 file, the entire .zip (.xlsx) file is actually encrypted using RSA encryption. It is no longer possible to change the extension to .zip and browse the file contents.
It's simply a matter of changing the filename extension to .ZIP, unzipping the file, and using any basic Hex Editor (like XVI32) to "break" the existing password, which "confuses" Office so it prompts for a new password next time the file is opened.
Microsoft Office VBA Project passwords are not to be relied upon for security of any sensitive information. If security is important, use third-party encryption software.
In the event that your block of CMG="XXXX"\r\nDPB="XXXXX"\r\nGC="XXXXXX"in your 'known password' file is shorter than the existing block in the 'unknown password' file, pad your hex strings with trailing zeros to reach the correct length.
For Excel 2007 onward you need to change your file extension to .zipIn the archive there is a subfolder xl, in there you will find vbaProject.bin.Follow the step above with vbaProject.bin then save it back in the archive.Modify back your extension and voil! (meaning follow steps above)
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.
If the file is a valid zip file (the first few bytes are 50 4B -- used in formats like .xlsm), then unzip the file and look for the subfile xl/vbaProject.bin. This is a CFB file just like the .xls files. Follow the instructions for the XLS format (applied to the subfile) and then just zip the contents.
Tom - I made a schoolboy error initially as I didn't watch the byte size and instead I copied and pasted from the "CMG" set up to the subsequent entry. This was two different text sizes between the two files, though, and I lost the VBA project just as Stewbob warned.
Using HxD, there is a counter tracking how much file you're selecting. Copy starting from CMG until the counter reads 8F (hex for 143) and likewise when pasting into the locked file - I ended up with twice the number of "..." at the end of the paste, which looked odd somehow and felt almost unnatural, but it worked.
I don't know if it is crucial, but I made sure I shut both the hex editor and excel down before reopening the file in Excel. I then had to go through the menus to open the VB Editor, into VBProject Properties and entered in the 'new' password to unlock the code.
ElcomSoft makes Advanced Office Password Breaker and Advanced Office Password Recovery products which may apply to this case, as long as the document was created in Office 2007 or prior.
The protection is a simple text comparison in Excel.Load Excel in your favourite debugger (Ollydbg being my tool of choice), find the code that does the comparison and fix it to always return true, this should let you access the macros.
The truth is that the code files for most macro-enabled Office documents are not encrypted and the password only prevents opening the project with Office programs.This means that, as other answers suggested, you can usually use an Office alternative to access and edit the file.
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.
For Excel 2016 64-bit on a Windows 10 machine, I have used a hex editor to be able to change the password of a protected xla (have not tested this for any other extensions).Tip: create a backup before you do this.
I am running into issues with the redirect. When I click on the link in the email, it takes me to my website home page rather than the page I entered into the redirect setting, and there is no token in the url. Could this be because I am testing in the editor, there the url is a weird format? Or is this caused by some other reason?
If you hover over the URL in the email, do you see the editor URL or the homepage URL? (Trying to figure out if the editor URL could be redirecting to your published homepage. Not sure how that could happen but worth checking!)
Hi,
I would like to install keepass in my employees PC so that they do not need to remember all passwords to our applications.
I provide them with the passwords , but I dont want them to change it or the be able to view it each time via the "show/hide passwords" feature in keepass. Just copy it to our applications to log.
Is that possible to do with Keepass, is it possible to prevent them from editing the entry again once we create it ? Thank you
Paul, I don't know why, but when I try to view the original post, I see only your reply, and not Andy's post that started the thread. (This has happened with several other threads over the past few months as well.) When I view the source of that page, I don't see any tag #ca6c nor any evidence of remnants from that post. Also, on the topic list, the other topic is listed as having only one post. I don't know what's going on there, but I'd suggest continuing this discussion here instead.
You can restrict visitors access to your online store by adding the password page in the Password protection section. The password page is a landing page that requires any visitor to provide a password to visit your online store. If you want your customers to access your online store, then you can provide them with the password to your online store.
When your password page is active, only the password page of your online store is found by search engines. Other pages, like product pages, are hidden, and search engines won't display these pages in search results.
In Password, enter the password that you'll give to the customers who you want to be able to access your online store. Don't use the same password that you use to log into your admin.
You can only remove password protection from your online store after you pick a pricing plan. If you pick a plan while you are on a free trial, then you won't be charged any subscription fees until your free trial expires.
There are two ways to remove your online store password: from your Themes page or from the Preferences page under Online Store in your Shopify admin.
The password.liquid file in the Templates directory is included in your theme by the content_for_layout Liquid tag, which is found in the password page layout file. To make any changes to the password page layout file, click password.liquid in the Layout directory.
