cryptmount – managing encrypted file systems

cryptmount is a software tool for managing encrypted file systems under Linux.

It uses the device mapper and dm-crypt infrastructure to provide transparent encryption of file systems stored in disk partitions or within ordinary files.

cryptmount is free and open source software.

Features include:

  • Interactive setup script is supplied to allow basic, but effective, encrypted file systems to be created.
  • Filesystems can be (un)mounted whenever needed by ordinary users, without requiring superuser/administrator privileges.
  • Multiple encrypted filesystems can be stored within a single disk partition. Encrypted swap partitions are supported and can be configured automatically on system boot-up.
  • Configuration information about encrypted filesystems is stored within a free-format human-readable file.
  • Access keys can be protected by a wide range of encryption and hashing algorithms provided by the libgcrypt library, which can be compatible with the OpenSSL command-line tool. They can be stored and backed-up separately from the filesystem that they protect.
  • Access to improved functionality in the kernel.
  • Transparent support for filesystems stored on either raw disk partitions or loopback files.
  • Separate encryption of filesystem access keys, allowing access passwords to be changed without re-encrypting the entire filesystem.
  • Storing multiple encrypted filesystems within a single disk partition, using a designated subset of blocks for each.
  • Rarely used filesystems do not need to be mounted at system startup.
  • Un-mounting of each filesystem is locked so that this can only be performed by the user that mounted it, or the superuser.
  • Encrypted filesystems compatible with cryptsetup.
  • Encrypted access-keys can be chosen to be compatible with openssl, or managed via libgcrypt, or built-in SHA1/Blowfish ciphers.
  • Support for encrypted swap partitions (superuser only).
  • Support for setting up encrypted filesystems or crypto-swap at system boot-up.
