How To Fix Error (The Specified File Could Not Be Decrypted)
Method 1: Obtaining Full Permission To Access File
This method gives full permission to access the system files and then follow one of the internal decrypting methods to unlock the files. But make sure that this method will not work in those cases where the file was originally encrypted on a different machine.
Simply follow the instructions on the PC where the file was originally encrypted. After completing them, simply move the file and open it on a different PC.
Many users fix the 0x80071771 error after following the instructions below. Come let’s take a look:
Head over to the File Explorer. Then right-tap on the drive letter that you’re encountering the error with and then select choose Properties.

Method 2: Import Or Export EFS File Encryption Certificate + Key
The only method that lets you open an encrypted file (EFS file) on a different PC is to import it along with the certificate and key. Any individual app that doesn’t have the appropriate file encryption key can’t be able to open it.
But if the method is applicable, you should access the PC computer that can be used to encrypt the file and export the key + certificate. Come let’s take a look:
Export EFS Certificate + Key
Hit Windows key + R to open up a Run dialog box. Then, input “certmgr.msc” and hit Enter to open the Certificates Manager utility.
In the Certificates Manager utility, choose Certificates from the left-hand pane and then tap on Personal. Then, head over to the right-hand side panel and double-tap on Certificates.
Right-tap on the Certificate that you want to import to the new PC and select All Tasks > Export.
Tap Next on the first screen and select Yes, export the private key at the other screen.
Choose Personal Information Exchange – PKCS #12 and make sure that the boxes linked with Include all certificates in the certification path, Enable certificate privacy, and Export all extender properties are marked. Then, press Next to move to the other screen.
Then set a password for the PFX file and then confirm it. Make sure to leave the encryption to TripleDES before tapping Next again.
Press the Browse button and then set a location where you like the PFX file to be saved. Then, tap Next once again.
At last, tap Finish to complete the process.
Import EFS File Encryption Certificate & Key:
The instructions given below will show you how to import the PFX file that is used for your file encryption certificate. Also, the key used with the EFS on a different PC. There are two different ways that you can use to import that certificate + key.
Both methods will work for any variant of Windows 10, so follow the one that is applicable to your current situation:
Import EFS File Encryption Certificate & key Through PFX file
After you retrieve the PFX file from the first PC, move it to the one where you’re encountering the 0x80071771 error on.
When the PFX file has been moved to the new PC. Simply right-tap on it and select Install PFX.
Under Store Location, select Current User and press Next to proceed.
Make sure the exact PFX file is chosen from the File to Import window and then tap Next once again.
On the other screen, input the password that you used whenever you encrypted the file under the Password field. Then, mark the boxes linked with Mark this key as exportable and Include all extended properties.
Then, choose the toggle linked with Automatically choose the certificate store based on the type of certificate and then tap next once again.
Note: You might view a Security warning if Windows can’t validate the certificate. When it happens and you trust the file origins, tap Yes to confirm.
Tap Finish to confirm the importing process. At the last prompt, tap Ok to apply the final confirmation.
