Remove Password From Pdf File After Opening

[Matthias Briggs]

Ireceived 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.

All of these posts mentioning special software look to me like advertisements for software no one needs. All you have to do is (a) rename the file in Preview or (b) print PDF from Preview, or (c in Preview press File/Export as PDF. All of these remove the need for a password.

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.

Remove pdf file password on Mac is not a easily question,unless you use some good tools or software,I know a tool can help you Remove pdf file password on Mac computer,you can try to try iStonsoft PDF Password Remover for Mac,This is a normal tool, very stable, simple operation, and fast speed,Believe it can help you Remove pdf file password on Mac and success!

Honestly, none of these programs mentioned above worked for me. May be they do not work with the latest version of protected PDF files. This is the only thing -pdf-restrictions-mac that helped me to get rid of pdf password restrictions on my MacBook Pro.

I've got lots of PDF files on my Mac computer, many of which contain passwords! This problem troubled me a lot when i wanted to use these files, but finally i found this guide - How to Unlock PDF Password on Mac, which solved my problems! And so i can now read them easily with the help of iPubsoft PDF Password Remover for Mac!

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.

Can you make a little example of what you mean? If you have a dataset that is password-protected, and want to create a view which allows a user of the view to use read data from the dataset without specifying a password, then you can provide the password for the dataset when you create the view, e.g. :

It's also possible to create a view that has a password, independent of the password for the dataset that it accesses. In that cases, you can use PROC DATASETS to remove the password from the view. So below I create a view with a password, and then use PROC DATASETS to remove the password from the view.

In that case work.class has a password. When you created the view v_class you did not specify the password for work.class. So even if you remove the password for v_class, you still need to specify the password for work.class when you use the view.

Is not about a password on the view mylib.dataset1 itself. It may result from a password on the underlying dataset, or other problems accessing the underlying dataset. Thus your PROC DATASETS step has (apparently) successfully removed any passwords that were on your view mylib.dataset1.

there is no log because all I do after using your code for example is I open a new session and point to the lib where the view is and it cant open without a password. Below error message: SQL View mylib.dataset1 could not be processed because at least one of the data sets, or views, referenced directly (or indirectly) by it could not be located, or opened successfully.

In order to help debug this problem, you need to have a reproducible problem. For example, a small reproducible example might be a program makeview.sas which creates a password-protected sas dataset mylib.foo and creates a permanent view mylib.v_foo with no password. And you run that program and get a clean log, and the view is created. Then you open program useview.sas in a new SAS session and you attempt to use the view and get the error. In that case, I'm asking you to post the code for makeview.sas and useview.sas and the log you get from running both programs.

You are running code to create the permanent SAS dataset that is password protected and create the permanent view you want to be unprotected, right? If so, please post that code, and the logs from running the code. Showing that both the password protected dataset and the view were created successfully. Please include the libname statements in the code.

That would be a small, reproducible example. Then I could take your code, update the libname statement to point to C:\Junk on my PC, and I should be able to run the code to create a permanent dataset and a permanent view. Then I can start a new SAS session and open the view, and see if I get the same error.

Unlocking a password requires you to have the appropriate permissions. No pdf password remover will work if you don't have those. Alternatively, you'll need to locate a policy author or administrator of the secured PDF to make this happen. Then, follow these steps:

There are many reasons why people might need to remove a pdf password, but oftentimes they avoid even asking the question. While it might seem suspicious, more often than not passwords need to be removed for benign purposes.

In the Changes Allowed menu, you can prevent all changes, keep users from inserting, deleting, and rotating pages, and restrict access to form and signature fields. Comments can also be restricted. And, if ultimately you end up not needing any restrictions at all, a PDF password remover or the steps above will help.

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.
