cryptsetup is a utility used to conveniently set up disk encryption based on the DMCrypt kernel module.
cryptsetup offers a command-line interface to set up cryptographic volumes. This is achieved using the Linux kernel device mapper target dm-crypt. It has integrated support for LUKS.
cryptsetup is backwards compatible with the on-disk format of cryptoloop, but also supports more secure formats. This package includes support for automatically configuring encrypted devices at boot time via the config file /etc/crypttab.
Additional features are cryptoroot support through initramfs-tools and several supported ways to read a passphrase or key.
Key Features
- Provides commands to deal with the Linux Unified Key Setup (LUKS) on-disk format.
- Key management.
- Key stretching.
- Remembers encrypted volume configuration across reboots.
