Questions About How to Decrypt A File
Q1: 'I recently encrypted some of my files in Windows 10 and kept my encryption key in my Documents folder in C drive. /powerpivot-free-install-mac/. I reinstalled Windows OS the other day, and the encryption key was lost due to formatting. Can I decrypt the file without the certificate?'
Q2: 'Unknown viruses encrypted all files and folders on my USB pen drive. I was threatened to pay Bitcoin to recover encrypted files, which I don't want to. I need a way to decrypt encrypted files without a password.'
Usage Guide - RSA Encryption and Decryption Online. In the first section of this tool, you can generate public or private keys. To do so, select the RSA key size among 515, 1024, 2048 and 4096 bit click on the button. This will generate the keys for you. For encryption and decryption, enter the plain text and supply the key. Read its readme on how to do this. Put the SD card into the 3DS. From the root GodMode9 menu, navigate to C: GAMECART. Select TitleID.trim.3ds, then select NCSD image options., then select Decrypt file (0:/gm9out). Once this process completes, the game will be a.3ds file inside /gm9/out/ and is immediately usable with Citra. GodMode9 is a full access file browser for the Nintendo 3DS console, giving you access to your SD card, to the FAT partitions inside your SysNAND and EmuNAND and to basically anything else. Among other functionality (see below), you can copy, delete, rename files and create folders.
In this article, we will provide a full guide about how to decry a file online without a key. And more, if your files encrypted by ransomware, use the robust data recovery tool and get your files back in a click.
Part 1. How to Decrypt a File Online Without Key/Certificate/Password
You can decrypt a file online without a key if you have the right tool. Advanced Encryption Standard(AES) is a symmetric encryption algorithm. Following is the example of generating an AES encrypted password and decrypt an AES encrypted password.
Part 2. How to Decrypt a File Without Password/Key/Certificate Offline
You can decrypt the files system by unchecking the 'Encrypt Contents to Secure Data' feature. But this only works for the file system, not your specific file. If you want to decrypt files, the certificate or password is indispensable.
If you haven't exported and backed up the file encryption certificate before or if you have forgotten the password, you cannot decrypt encrypted files in the following situations.
- Moving encrypted files to another computer
- Recovering data from an encrypted disk
Suppose that you really need to decrypt files, lots of guides will advise you to try the online decryption tools. However, you need to be aware that these tools are not 100% safe. You may be at risk of data theft or source data corruption.
In addition to this case, where users actively use tools to encrypt, there is another unexpected way of files being encrypted, which is by viruses or ransomware. For example, ransomware encrypts and deletes files. In the next part, we will show you how to use a reliable ransomware encrypted file recovery tool to get back data without paying the ransom.
Here, we show you three helpful ways to recover files deleted or encrypted by ransomware like Locky, CryptoLocker, CryptoWall, and TorrentLocker, without paying.
Part 3. How to Recover Encrypted Files Locked by Ransomware
Since most ransomware encrypts your files and folders by three steps: make an exact copy of files and folders > encrypt the copy > delete the source files. How this works gives you a great opportunity to recover the encrypted files through professional data recovery software.
Here, we highly recommend you try EaseUS Data Recovery Wizard. This virus attack data recovery program enables you to recover files infected by shortcut virus, restore files deleted and encrypted by ransomware like Locky, CryptoLocker, CryptoWall, and TorrentLocker, without paying.
EaseUS Data Recovery Wizard
- Recover lost or deleted files, documents, photos, audio, music, emails effectively
- Recover files from SD card, emptied recycle bin, memory card, flash drive, digital camera, and camcorders
- Support data recovery for sudden deletion, formatting, hard drive corruption, virus attack, system crash under different situations
Now, download this capable data recovery tool and start to recover ransomware encrypted files within three steps. Note that this is just for file recovery of shortcut virus or ransomware, not including those by encryption tools.
Step 1. Select the virus infected drive to scan
Run EaseUS virus file recovery software on your Windows PC.
- If it's an HDD where files were hidden or deleted by virus, it's better to install the software on a different volume or an external USB drive to avoid data overwriting.
- If the infected device is an external hard drive, flash drive or memory card, it doesn't matter to install the software on the local drive of the computer.
Select the correct drive according to its drive letter and click Scan.
Step 2. Wait for the scan results
The software will immediately start a scan process to find your lost files on the virus infected hard drive. Do not stop the deep scan until all lost files show up. To quickly locate the wanted files, you can use the Filter feature to display only the pictures, videos, documents, emails, etc.
When the process finishes, you can double-click files to preview their contents.
Step 3. Select file(s) to recover
Select the files you want and click the Recover. You should save these files to another safe spot on your PC/storage device, not where they were lost.
Enter Decryption Key
- 1. Unformat the drive
- 2. Repair the RAID, RAW disk, or operating system
- 3. Recover lost partition (the one that cannot be recovered by software)
Part 4. How to Encrypt a File in Windows 10/8/7
Sometimes we tend to protect privacy by using some file encryption tools, such as EFS (Encrypting File System), which provides the core file encryption technology used to store encrypted files on NTFS file system volumes. So only with a certificate can people access the EFS locked files.

Steps to encrypt a file in Windows 10/8/7
Step 1. Find the file or folder you wish to encrypt.
Step 2. Right-click the file/folder and click 'Properties.' Then, click the 'Advanced..' button on the General screen.
Step 3. Check the box 'Encrypt Contents to Secure Data' under the Compress or Encrypt attributes section, then click the 'OK' button.
Step 4. Continuing to click the 'OK' button. An encryption warning box will pop up.
Step 5. Check the 'Encrypt the File Only' box to encrypt the individual file, then click 'OK' to finish.
Note: If you copy unencrypted files to a folder with encrypted property, they will be automatically encrypted.
EFS encryption is transparent. If you encrypt some data, you can access this data without any restriction.
To Sum Up
You can use EFS or Bitlocker to encrypt your files and data. But to avoid losing the password, key, or certificate and not being able to decrypt files, we suggest you back up your encryption certificates and keys to a safe location, and remember your EFS backup password.
For solving the encryption problem caused by ransomware, the most important thing is preventing virus infection. Install and enable the anti-virus software on your computer. Moreover, back up important data and files on your computer regularly.

How to Dump and Decrypt 3DS Cartridges
You must have a 3DS for this, you cannot use a PC alone.
Note on DLC and updates
Dumping a cartridge does not dump DLC and updates for that cartridge. Those are stored on the SD card. See Dumping Installed Titles for more information.
With the onset of sighax and boot9strap, the supported method of dumping game cartridges is GodMode9.
- 3DS system with boot9strap
- SD card with enough space to hold the dump; 8GB or higher recommended
- SD card reader (preferred), or a way to use wireless file transfer
- Set up GodMode9 using SigHax / Boot9Strap. Read its readme on how to do this.
- Put the SD card into the 3DS.
- From the root GodMode9 menu, navigate to
[TitleID].trim.3ds, then select
NCSD image options.., then select
Decrypt file (0:/gm9out).
- Once this process completes, the game will be a .3ds file inside
/gm9/out/and is immediately usable with Citra.
There was an error with dumping
- Make sure you are using the latest version of GodMode9.
