Why Use EFDD?How Does EFDD Work?
EFDD works by extracting the encryption keys from various sources and using them to decrypt the data or mount the volumes. EFDD supports the following encryption types and data sources:
Supported Encryption Types
BitLocker: This is the built-in encryption feature of Windows, which can encrypt entire disks, partitions, or removable drives. BitLocker uses AES encryption with 128-bit or 256-bit keys.
FileVault 2: This is the built-in encryption feature of macOS, which can encrypt the startup disk or external drives. FileVault 2 uses AES encryption with 128-bit or 256-bit keys.
PGP Disk: This is a commercial encryption software developed by Symantec, which can encrypt entire disks, partitions, or virtual disks. PGP Disk uses various encryption algorithms, such as AES, Twofish, Blowfish, CAST, or Triple DES.
TrueCrypt: This is a discontinued open-source encryption software, which can encrypt entire disks, partitions, or virtual disks. TrueCrypt uses various encryption algorithms, such as AES, Serpent, Twofish, or combinations of them.
VeraCrypt: This is an open-source encryption software that is based on TrueCrypt, which can encrypt entire disks, partitions, or virtual disks. VeraCrypt uses various encryption algorithms, such as AES, Serpent, Twofish, Camellia, or combinations of them.
LUKS/LUKS2: This is a standard format for Linux disk encryption, which can encrypt entire disks or partitions. LUKS/LUKS2 uses various encryption algorithms, such as AES, Serpent, Twofish, Camellia, or ChaCha20.
Jetico BestCrypt: This is a commercial encryption software developed by Jetico, which can encrypt entire disks or virtual disks. Jetico BestCrypt uses various encryption algorithms, such as AES, Blowfish, Twofish, GOST 28147-89, or IDEA.
Supported Data Sources
RAM captures: These are memory dumps that contain the contents of the system's RAM at a certain point in time. RAM captures can be obtained from live systems using tools such as Elcomsoft Memory Dumper (included with EFDD), Belkasoft Live RAM Capturer (free), FTK Imager (free), or WinHex (commercial). RAM captures can contain encryption keys for BitLocker, FileVault 2, PGP Disk, TrueCrypt, VeraCrypt, LUKS/LUKS2 and Jetico BestCrypt.
Hibernation files: These are files that store the contents of the system's RAM when the system enters hibernation mode. Hibernation files can be found on the system drive (usually C:\hiberfil.sys for Windows or /var/vm/sleepimage for macOS). Hibernation files can contain encryption keys for BitLocker, FileVault 2, PGP Disk, TrueCrypt and VeraCrypt.
Page files: These are files that store the contents of the system's virtual memory when the system runs out of RAM. Page files can be found on the system drive (usually C:\pagefile.sys for Windows). Page files can contain encryption keys for BitLocker and PGP Disk.
Escrow keys: These are backup keys that are stored in a secure location and can be used to decrypt the data in case of password loss. Escrow keys can be obtained from Active Directory (for BitLocker) or iCloud (for FileVault 2).
Recovery keys: These are backup keys that are generated by the encryption software and can be used to decrypt the data in case of password loss. Recovery keys can be printed on paper, saved as a file, or stored in a USB drive. Recovery keys are available for BitLocker and FileVault 2.
Supported Output Formats
Decrypted files and folders: EFDD can decrypt individual files and folders stored in encrypted containers and save them as regular files on another drive. This option is available for PGP Disk and Jetico BestCrypt containers.
Mounted volumes as drive letters: EFDD can mount encrypted volumes as new drive letters on the system and provide instant access to their contents. This option is available for BitLocker, FileVault 2, PGP Disk, TrueCrypt and VeraCrypt volumes.

Step-by-Step Guide
To demonstrate how to use EFDD, we will use an example scenario where we need to decrypt a BitLocker volume with a recovery key. The steps are as follows:
Launch EFDD and click on the Open button on the toolbar. A dialog box will appear where you can select the source of the encrypted volume. You can choose from Physical Device (if the volume is on a physical disk), Logical Drive (if the volume is on a logical drive), or Disk Image (if the volume is on an image file).
Select the source of the encrypted volume and click OK. EFDD will scan the source and display the encrypted volume in the main window. You can see that the encryption type is BitLocker and the status is Locked.
Select the encrypted volume and click on the Decrypt button on the toolbar. A dialog box will appear where you can select the method of decryption. You can choose from Memory Dump (if you have a RAM capture that contains the encryption key), Password (if you know the password of the volume), Recovery Key (if you have a recovery key for the volume), or Escrow Key (if you have an escrow key for the volume).
Select Recovery Key as the method of decryption and click Next. A dialog box will appear where you can enter or browse for the recovery key file. The recovery key file is usually a text file with a .bek extension that contains a 48-digit numerical code.
Enter or browse for the recovery key file and click Next. EFDD will verify the recovery key and start decrypting the volume. You can see the progress and status of the decryption in the status bar.
When the decryption is complete, you will see a message that says "Decryption complete". You can also see that the status of the volume is Unlocked in the main window.
Select the decrypted volume and click on the Mount button on the toolbar. A dialog box will appear where you can select a drive letter for the mounted volume. You can also choose to mount the volume as read-only or writable.
Select a drive letter and click OK. EFDD will mount the volume as a new drive letter on your system and provide instant access to its contents. You can see the drive letter in the main window and in Windows Explorer.
You can now browse, copy, or modify the files and folders on the mounted volume as if it was a regular drive. You can also use other tools to analyze or recover the data on the volume.
When you are done with the mounted volume, you can unmount it by selecting it and clicking on the Unmount button on the toolbar. EFDD will unmount the volume and remove the drive letter from your system.
That's how you can use EFDD to decrypt a BitLocker volume with a recovery key. You can use similar steps to decrypt other types of encrypted volumes or containers with different methods of decryption.

Frequently Asked Questions about EFDD
Here are some frequently asked questions about EFDD features and functionality:
What is the difference between decrypting and mounting?
Decrypting means extracting the encrypted data from an encrypted volume or container and saving it as regular files on another drive. Mounting means attaching an encrypted volume or container as a new drive letter on your system and providing instant access to its contents. Decrypting requires more disk space and time than mounting, but it allows you to access the data offline or on another system. Mounting requires less disk space and time than decrypting, but it requires the encrypted volume or container to be accessible and intact. You can choose the option that suits your needs and preferences.
Can I decrypt or mount multiple volumes or containers at once?
Yes, you can decrypt or mount multiple volumes or containers at once with EFDD. You can select multiple items in the main window and click on the Decrypt or Mount button on the toolbar. EFDD will process each item in the order of selection and display the results in the main window and the status bar.
Can I pause or cancel the decryption or mounting process?
Yes, you can pause or cancel the decryption or mounting process with EFDD. You can click on the Pause or Cancel button on the toolbar to stop the current operation. You can resume the paused operation by clicking on the Resume button on the toolbar. You can also abort the operation by closing EFDD.
Can I use EFDD on encrypted volumes or containers that are damaged or corrupted?
EFDD can handle some minor damage or corruption on encrypted volumes or containers, such as bad sectors, file system errors, or partial encryption. However, if the damage or corruption is severe, EFDD may not be able to decrypt or mount the data. In such cases, you may need to use other tools to repair or recover the data before using EFDD.
Can I use EFDD on encrypted volumes or containers that are protected by additional security measures?
EFDD can bypass some additional security measures on encrypted volumes or containers, such as pre-boot authentication, hidden volumes, or plausible deniability. However, if the security measures are too complex or unknown, EFDD may not be able to decrypt or mount the data. In such cases, you may need to use other methods to access the data, such as brute-force attacks, dictionary attacks, or social engineering.
