1. How To Delete Winrar

Anyway, I haven't been able to find an answer to this question. I know the password to the RAR file, I locked it myself, but now all I want to do is remove the password because it's too much of a pain in the butt to type it in every time. 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. It's not a life-or-death issue, but it would be nice to know. Thanks for your time!

EDIT: I just saw a bunch of related questions that appear to ask the same thing. The only solution I saw was using a DOS command to yadda yadda yadda. Here it is: Is there an easier way? Thanks again! Out of the box, no, you can not.

Level of difficulty: Beginner WinRAR is defined as a 32-bit Windows-based archiver and archive manager used to create compressed files similar to the way it is. When you forgot Winrar Password and can’t extract. A Winrar (a file with. Just download the trail and try to remove password protected RAR archive all.

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. You could make a quick batchfile implementing a 'remove password' feature, which could simply unrar the archive, and then re-compress the files without a password. Technically, the data is compressed before being encrypted. This indicates that, given enough knowledge of the RAR file format itself, one could create a tool to AES-decrypt the datastream of the compressed files, and then save it into a new RAR archive. It should be noted, however, that this requires extensive knowledge of the file format itself.

Given the number of open-source tools that support password-protected RAR files (e.g. ), 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). @Random832 yes sorry, I see that was poorly worded now.

I updated the answer just now to hopefully get my thoughts across a bit more clear. After further research, this does to be technically possible given enough knowledge of the RAR format.

Although as you said, obscure enough to be omitted (not to mention the proprietary nature of the RAR format complicates things). However, if anyone does want to get into it, I provided a link to an example open-source tool ( unar) which can decrypt encrypted RAR archives. – Aug 2 '13 at 13:34.
