How does Ubuntu disk encryption work?

The encryption (LUKS) works on blocks of data, can randomly decrypt any block, and acts like a layer between the drive's encrypted data and what the filesystem sees. When the filesystem wants to see any block of data, LUKS decrypts that block first and then gives the decrypted data to the filesystem.

What is eCryptfs Ubuntu?

eCryptfs (Enterprise Cryptographic Filesystem) is a package of disk encryption software for Linux. Its implementation is a POSIX-compliant filesystem-level encryption layer, aiming to offer functionality similar to that of GnuPG at the operating system level, and has been part of the Linux kernel since version 2.6.19.
