Cryptsetup 2.6 Released With Support For Apple FileVault2

Written by Michael Larabel in Linux Storage on 29 November 2022 at 06:15 AM EST. 10 Comments
Cryptsetup 2.6 is now available as the newest version of this utility for managing disk encryption on Linux systems in conjunction with the DMcrypt kernel module.

The most notable change with the Cryptsetup 2.6 release is now support for dealing with Apple FileVault2 devices. Cryptsetup is now able to deal with the mapping of FileVault2 full-disk encryption used by Apple. This includes the ability to open an existing USB FileVault-protected portable device from Linux and -- with the HFS+ file-system driver support present -- access the native data read/write.

As of Cryptsetup 2.6 there is just support for FileVault2 using Core Storage and HFS+ but not the new FileVault based on the newer APFS file-system with the latest macOS versions.

Cryptsetup 2.6 also no longer uses global memory locking via mlockall(), new APIs, and a variety of fixes and other improvements to this widely-used utility for dealing with encrypted storage under Linux.

Downloads and more details on the Cryptsetup 2.6 changes via cryptsetup on GitLab.
