However, there is a possibility that encrypted RAR file password is forgotten or lost and there is no password backup. When this happens unfortunately, please go on to see the situation 2 which is about how to extract encrypted RAR file without password.

Step 8: In Extraction path and options window, under General option, select or create a location in Destination path to save archive file you prepare to extract. Click OK and a new dialog appears and asks for RAR archive password.

Be cautious when sharing files or passwords with other users. You still run the risk of passwords them falling into the hands of unintended users. Remember that locking a file with a password does not necessarily protect your file from malicious intent.
If you're concerned about end-users in your organization losing access to password protected Office files, the DocRecrypt tool might be for you. Note that you have to deploy the DocRecrypt tool BEFORE the file in question is password protected. DocRecrypt can't retroactively recover files that were password protected before you deployed DocRecrypt. For more information see: Remove or reset file passwords using DocRecrypt.
It's possible to force the user to supply a password to encrypt RAR archives so a file can be extracted. If you have an encrypted archive for which you don't know the password, or if you've simply forgotten a password you assigned yourself, there are a handful of tricks you can attempt.
Check the source of the archive. If you downloaded it from a website, look around the site for a mention of the password (after all, it's unlikely someone offered an unopenable archive for download.) If the person you downloaded it from can be contacted, send them an email asking for the password.
Select "Brute Force Attack" and click "Next". Set a "Maximal length", the maximum number of characters you think are in the password, and a charset, which is the characters the password is likely to use.
When FileVault is turned on, your Mac requires your user account password to unlock your built-in startup disk and allow your Mac to finish starting up. No user account is permitted to log in automatically. Follow the appropriate steps based on the version of macOS you're using.
When you turn on FileVault, you can choose how you want to be able to unlock your disk and reset your password in case you ever forget your password. For example, you can use your iCloud account or use a recovery key. Learn more about these options.
If other users have accounts on your Mac, you're prompted to enable each user and enter their password before they can unlock the disk. User accounts added after turning on FileVault are automatically enabled.
To change the recovery key used to encrypt your startup disk, first turn off FileVault, which requires your account password. You can then turn it on again to generate a new key and disable all older keys.
When you format an internal or external storage device, you can encrypt and protect it with a password. If you encrypt an internal device, you must enter a password to access the device and its information. If you encrypt an external device, you must enter the password when you connect the device to your computer.
You can limit access to a PDF by setting passwords and by restricting certain features, such as printing and editing. However, you cannot prevent saving copies of a PDF. The copies have the same restrictions as the original PDF. Two types of passwords are available:
If the PDF is secured with both types of passwords, it can be opened with either password. However, only the permissions password allows the user to change the restricted features. Because of the added security, setting both types of passwords is often beneficial.
Type and retype your password. Your password must be at least six characters long. The password strength is displayed next to your password to indicate whether the chosen password is weak, medium, strong, or best.
Select Require A Password To Open The Document, then type the password in the corresponding field. Your password must be at least six characters long. For each keystroke, the password strength meter evaluates your password and indicates the password strength.
The Compatibility option you choose determines the type of encryption used. It is important to choose a version compatible with the recipient's version of Acrobat or Reader. For example, Acrobat 7 cannot open a PDF encrypted for Acrobat X and later.
Choose Editing, and then type and retype your password. Your password must be at least six characters long. The password strength is displayed next to your password to indicate whether the chosen password is weak, medium, or strong.
You can prevent users from printing, editing, or copying content in a PDF. You can set the restrictions you want to apply to the PDF. Users cannot change these restrictions unless you give them password.
All Adobe products enforce therestrictions set by the permissions password. However, if third-partyproducts do not support these settings, document recipients areable to bypass some or all of the restrictions you set.
Type the password in the corresponding field. Your password must be at least six characters long. For each keystroke, the password strength meter evaluates your password and indicates the password strength.
Compressed files, also known as .zip files, are one of the most convenient ways of transferring data from one computer to another. You can essentially pack gigabytes upon gigabytes of files into a single place, then send it to just about anyone in a single transfer. Because of its great use, many people look to protect their .zip files with a password to ensure only those with permission can unpack the contents.
This guide focuses on showing you how to password protect .zip files on Windows 10, using all the best tools you could possibly need. Ensure that your files are in the right hands by applying a password only you know and only you can share.
Using the Encrypting File System (EFS) encrypts the data of your folder or .zip file and generates a decryption key that acts as a password. Only people with the exact, correct key will be able to decrypt the contents.
WinRAR is an application that allows you to create and manage .zip files, including password protection. The free trial allows you to indefinitely manage your compressed files, and regular updates ensure that your experience is always the best.
Note: Do not send the password for an encrypted file along with the file itself. For example, if you are sharing an encrypted file through an e-mail message, use a different means of communicating the password to the recipient, such as text or phone call.
You can set two passwords on the file - one to open the file as read-only, and the other to modify. Then you can share the appropriate passwords with the users depending on the access level they should have.
Read-only access does not prevent someone from making changes to a file, but it does prevent them from saving those changes unless they rename the file and save it as something other than the original. For users who need to be able to modify the file, you will have to share both open and modify passwords.
Remove password encryption:To remove password encryption from the file, open the workbook and enter the password in the Password box. Then click File > Info > Protect Workbook > Encrypt with Password. Delete the contents of the Password box, click OK, and then save the file again.
In some cases, when you attempt to unzip files from (extract) or view files in a Zip file (.zip or .zipx) a Decrypt dialog will display requesting a password. This indicates that the files in your Zip file have been encrypted.
The password for an encrypted Zip file is set by the person who creates the Zip file at the time it is created. It is also possible to encrypt files in a Zip file after the Zip file is created, but again the person choosing to encrypt is the one who sets the password.
