Arcanum

Arcanum is an Android application for working with encrypted container files, the kind of single-file volumes that hold a set of documents behind a passphrase. It is described as compatible with VeraCrypt, meaning containers created on a desktop with that tool are meant to be opened on the phone through Arcanum, and the reverse. The practical use case is carrying an existing volume between machines and a handheld device without converting it to a different format.

The app is published under the Apache-2.0 license and targets Android only, so there is no companion desktop build in this listing; a separate desktop implementation is needed at the other end of the workflow. The record here does not enumerate which ciphers, key derivation settings, or container features are covered, nor whether creation and read-only access differ in scope, so anyone relying on a specific volume configuration should confirm support against their own container before committing to it.
