Libfvde

libfvde is a library to access FileVault Drive Encryption (FVDE) (or FileVault2) encrypted volumes.

The FVDE format is used by Mac OS X, as of Lion (10.7), to encrypt data on a storage media volume.

Project information:

• Status: experimental
• Licence: LGPLv3+

Supported Core Storage / FileVault2 implementations:

• Mac OS X Lion (10.7)
• Mac OS X Mountain Lion (10.8)
• Mac OS X Mavericks (10.9)
• Mac OS X Yosemite (10.10)
• Mac OS X El Capitan (10.11)
• macOS Sierra (10.12)
• macOS High Sierra (10.13)
• macOS Mojave (10.14)
• macOS Catalina (10.15)

Supported encryption volume types:

• removable media volume - with encrypted context (initial support as of 20121113 version)
• system volume
• multiple logical volumes

Supported protection methods:

• password
• recovery password
• VMK key data (as of 20121114 version)

Unsupported Core Storage format features:

• multiple physical volumes

Work in progress:

• DEFLATE compressed XML plist
• removable media volume - without encrypted context
• removable media volume - decrypted
• extend CoreStorage volume support
• partial encrypted volumes

Planned:

• Dokan support
