Singularity 3.4.0 Enables Build and Run Encrypted Containers

Sylabs just released the Singularity 3.4.0. The major new feature of this release is the ability to build and run encrypted containers. "Singularity containers remain encrypted throughout their entire lifecycle - when they are created, when they are at rest or transferred around, and yes, even when they are in use. Owing to their use of kernel space for data decryption, there is no need to clean up a decrypted rootfs upon termination."
