WebNov 18, 2024 · There are many formats or types which dm-crypt/cryptsetup support (current version supports luks, luks1, luks2, plain, loopaes, tcrypt), but the most commons ones are LUKS1 and LUKS2, where LUKS2 is an obviously newer format, which uses argon2i by default. It is a less known fact that cryptsetup supports TrueCrypt/VeraCrypt as well. 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 ...
