It is a less known fact that cryptsetup supports TrueCrypt/VeraCrypt as well. WebData-at-rest encryption#Preparing the disk. Securely wipe disk. Before encrypting a drive, it is recommended to perform a secure erase of the disk by overwriting the entire drive with random data. To prevent cryptographic attacks or unwanted file recovery, this data is ideally indistinguishable from data later written by dm-crypt.

WebDecryption. In cryptography, encryption is the process of transforming information (referred to as plaintext) using an algorithm (called cipher) to make it unreadable to anyone except those possessing special knowledge, usually referred to as a key. The result of the process is encrypted information (in cryptography, referred to as ciphertext). WebMay 30, 2015 · Of course it refers to LUKS. That's what everyone uses. But it's the same principle for plain mode. Or you could mix the ideas, a LUKS encrypted key can still open a plain encrypted disk. @yaegashi's answer is the same idea again, only it uses gpg instead of cryptsetup to encrypt the key. –

If no problems occur, the contents of the encrypted block device should not be accessible directly from the block device. i.e., you should be able to mount it directly. WebThese include plain dm-crypt volumes and LUKS volumes. The difference is that LUKS uses a metadata header and can hence offer more features than plain dm-crypt. On the other hand, the header is visible and vulnerable to damage. In addition, cryptsetup provides limited support for the use of loop-AES volumes, TrueCrypt, VeraCrypt, BitLocker and ...
