RAR is an abbreviation for Roshal Archive. It is a file format developed by Eugene Roshal, a Russian software engineer. This archive file format provides computer users with a quick way to compress and secure files. Users can add a password while compressing files to ensure only intended users access the files. Unfortunately, this security feature is difficult to surmount when the user forgets the password. This can be quite inconvenient.
To make matters worse, WinRAR, the GUI-based version for Windows, uses a 256 bit AES encryption, which is hard to crack. So how do you decrypt a RAR file? Below are four methods that show you how to decrypt RAR files without password.
This method calls for the big guns. You have to download RAR password recovery software. There are several handy tools to do this, but PassFab for RAR is by far the best tool you can find online. This powerful RAR decrypter tool quickly recovers lost or forgotten passwords for RAR and WinRAR archives. It uses advanced GPU acceleration to speed up the process.
The tool is straightforward to use. Download the file from the website and install it on the computer. After that, double-click the PassFab icon on your desktop to launch the application. After that, you need to follow three easy steps to decrypt the RAR file without password.
It is also possible to decrypt RAR files without password using the Windows Command prompt utility. Please note that this is a technical process that can corrupt your files and even your PC. So, it is only recommended for highly adept Windows users.

Step 3: Double-click on rar-password.bat to launch the Windows command prompt utility. Then locate your encrypted RAR file, right-click, and click Properties. In the Details tab, take note of the file path.
RAR is a highly sophisticated technology used by many companies to secure documents when sharing them via email, collaboration tools, or physically in storage media. When you forget or lose a RAR password, your job or business prospects could be on the line. The only way to get out of such a jam is to use a professional RAR password decrypter. Although free online methods seem easy to use, they are not effective. Your best bet is a tool like PassFab for RAR. We hope this article has taught you how to decrypt RAR files without 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.
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. 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).
So yes, the data is encrypted. This is only one of the elements of security, however. Another important element is how the key is derived from the password: what kind of key strengthening is performed? The slower the derivation of the key from the password, the more costly it is for an attacker to find the password (and hence the key) by brute force. A weak password is toast anyway, but good key strengthening can make the difference for a reasonably complex but still memorable password. WinRAR uses 262144 rounds of SHA-1 with a 64-bit salt, that's good key strengthening.
The advantage of using the encryption built into the RAR format is that you can distribute an encrypted RAR archive to anyone with WinRAR, 7zip or other common software that supports the RAR format. For your use case, this is irrelevant. Therefore I recommend using a software that is dedicated to encryption.
The de facto standard since you're using Windows was TrueCrypt. TrueCrypt provides a virtual disk which is stored as an encrypted file. Not only is this more secure than WinRAR (I trust TrueCrypt, which is written with security in mind from day 1, far more than any product whose encryption is an ancillary feature), it is also more convenient: you mount the encrypted disk by providing your password, then you can open files on the disk transparently, and when you've finished you unmount the encrypted disk.Sadly TrueCrypt is no longer in active development but it's successor VeraCrypt is. VeraCrypt is based on TrueCrypt and is compatible with the old TrueCrypt containers.
So yes, using password protection encrypts your file too. 7-Zip uses AES-256 encryption. Another approach to protect your files could be creating encrypted file (or disk) using TrueCrypt, where you can choose encryption algorithm that suits your needs.
Different archive formats offer different levels of security, but they all suffer from the same flaw: you can't actually USE the file without extracting and unencrypting it. More importantly, this is done on-disk, which means a copy of your file without encryption remains on your computer. Programs like word tend to also create auto-save files which add even more unencrypted copies.
The Embedded File Extractor module opens ZIP, RAR, other archive formats, Doc, Docx, PPT, PPTX, XLS, and XLSX and sends the derived files from those files back through the ingest pipeline for analysis.
After ingest, you can attempt to decrypt these archives if you know the password. Find the archive (either in the tree view or result view) and right-click on it, then select "Unzip contents with password".
After entering the password, you can select which ingest modules to run on the newly extracted files. When finished, you can browse to the encrypted archive in the tree view to see the newly extracted files. If the archive was already open in the tree, you may have to close and open the case in order to see the new data.
You must have sufficient usage rights or be a super user for your organization to unprotect files. For more information, see Configuring super users for Azure Information Protection and discovery services or data recovery.
This command unprotects a folder, retaining the original protected files and creating the unprotected versions in the folder location named C:\Temp and creates a corresponding subfolder of "Protected".
In turn, these .msg files can be containers that hold attachments. Because the .pst file is a container, every child file and nested container are also unprotected by this operation.
This command unprotects a .rar archive file. Because .rar files are container files that hold nested files, these nested files can also be archives. Every child file and nested container are also unprotected by this operation.
The file or the files in the specified folder are unprotected in the current location, replacing the original protected file or files. This parameter is ignored if the OutputFolder parameter is specified.
Specifies the path and base file name, with optional file name extension for log files. These log files list the files that are successfully or unsuccessfully unprotected. The following three log files are created for success, failure, and debug respectively:
If you do not specify this parameter, the log files Success.log, Failure.log, and Debug.log are written to the default log file location of %localappdata%\Microsoft\MSIPC\pscmdlet\Logs[GUID].
Advanced Archive Password Recovery recovers protection passwords or unlocks encrypted ZIP, 7Zip and RAR archives created with all versions of popular archivers. Recover passwords for plain and self-extracting archives created with PKZip and WinZip, 7Zip, RAR and WinRAR automatically or with your assistance. Guaranteed unlocking of archives created with WinZip 8.0 and earlier in under one hour is possible by exploiting an implementation flaw.
Certain ZIP and ARJ archives can be unlocked and decrypted in just minutes, provided that you have at least one unprotected file from that archive at your discretion. It does not matter how long and complex the password is! If you have a file from the encrypted ZIP archive in your hands, the whole archive can be usually unlocked in minutes by applying the known-plaintext attack. Similar ARJ archives are unlocked instantly. Fast recovery available only in case of "classical" encryption, not AES. 2b1af7f3a8
