For tcrypt device type it restricts checked cipher chains when looking for header. cryptsetup --help shows the compiled-in defaults. If a hash is part of the cipher specification, then it is used as part of the IV generation. WebThe default cipher used for LUKS (refer to cryptsetup --help) is aes-cbc-essiv:sha256. Note that the installation program, Anaconda, uses by default the AES cipher in XTS mode, aes-xts-plain64. The default key size for LUKS is 256 bits. The default key size for LUKS with Anaconda (XTS mode) is 512 bits. Warning
