How To Decrypt Encrypted Data? - Newsoftwares.net Blog (2024)

To decrypt encrypted data, you need to use encryption software or specialized tools. Install the chosen software, locate the encrypted file or folder, and initiate the decryption process following the provided instructions

Decrypting encrypted data is essential when you need to gain access to protected files or share them with specific users. I will explore different methods for decrypting encrypted data, ensuring that you can unlock your secure files with ease. Whether you’re dealing with encrypted files on Windows or other platforms, we’ve got you covered. Dive in and discover the methods for decrypting encrypted data.

What Is Decryption And How It Works?

Decryption is the process of converting encrypted data back into its original, readable form. It involves reversing the encryption algorithm applied to the data using a decryption key or password. The decryption process essentially undoes the encryption process, allowing authorized users to regain access to the information.

Here’s how decryption works:

1. Encryption Algorithm: Encrypted data is created using an encryption algorithm, which scrambles the information according to specific mathematical functions and operations.
2. Encryption Key: During encryption, an encryption key is used to control the algorithm and transform the data into an unreadable format. This key is typically a long string of characters.
3. Decryption Key: To decrypt the data, the recipient or authorized user needs the corresponding decryption key. This key is generated by the encryption algorithm and is essential for reversing the encryption process.
4. Reversing the Algorithm: Using the decryption key, the decryption algorithm reverses the encryption process, transforming the encrypted data back into its original, readable form.
5. Accessing the Decrypted Data: Once the decryption process is complete, the authorized user can access and utilize the decrypted data as intended.

Decrypting Encrypted Data on Windows 10

Unlocking secure files and granting access to encrypted data is a task that requires a systematic approach. Below, we outline two methods to decrypt encrypted data on Windows 10.

Method 1: Exporting and Installing Certificates

Certificates play a vital role in decrypting encrypted data. In this method, we export a certificate from the encrypting user account and install it on the target user account.

1. Right-click on the encrypted folder and select “Properties.
2. In the “Properties” window, navigate to the “Advanced” tab.
3. Locate the “Details” section and identify the user account that created the encrypted files.
4. Export the certificate associated with the user account by following these steps: a. Open the Microsoft Management Console by typing “MMC” in the Run command. b. Go to “File” > “Add/Remove Snap-in” and select “Certificate” from the left-hand side. c. Choose “Create a certificate for my user account” and proceed. d. Save the certificate in a secure location, preferably on a USB drive.
5. Provide the exported certificate to the user account that requires access to the encrypted files.
6. Install the certificate on the target user account by following these steps: a. Log in to the target user account. b. Double-click the exported certificate and select “For Current User.” c. Enter the password associated with the certificate. d. Choose the option to automatically select the certificate store. e. Complete the certificate import wizard.
7. The target user account can now access the encrypted files.

Method 2: Utilizing BitLocker for Decryption

Windows 10 Pro offers the BitLocker feature, which simplifies the process of decrypting encrypted data. This method is ideal for users with Windows 10 Pro.

1. Right-click on the encrypted file or folder and select “Properties.”
2. In the “Properties” window, navigate to the “General” tab.
3. Locate the “Encrypt contents to secure data” option.
4. Uncheck this option to initiate the decryption process.
5. Click “OK,” then “Apply,” and finally “OK” to confirm the changes.
6. If a password was set during encryption, enter the password to complete the decryption.

Using Command Prompt for Decryption

For those well-versed in using Command Prompt, an alternative method for decryption is available. This approach can be useful in specific scenarios.

1. Right-click on the encrypted file and select “Properties.”
2. Note the file type (e.g., .MP4).
3. Open Notepad by pressing the Windows button and typing “note.”
4. Copy the file type (e.g., .MP4) and the full address of the file.
5. Open Command Prompt as an administrator.
6. Type “cipher /d” and enclose the full address in double quotes.
7. Press Enter to initiate the decryption process.
