WebIf --size (in 512-bytes sectors) or --device-size are not specified, the size is computed from the underlying device. For LUKS it is the size of the underlying device without the area reserved for LUKS header (see data payload offset in luksDump command). For plain crypt device, the whole device size is used. WebNote: With the optional parameter --sector-size, you can set the size of the blocks to be encrypted or decrypted. It must be a power of two and in the range 512 - 4096 bytes. cryptsetup chooses a default sector size of 512 bytes. Using 4096-byte sectors provides the best performance on Linux on Z and LinuxONE.
