Cryptsetup sector size
WebUse as the encryption unit instead of 512 bytes sectors. This option can be in range 512 - 4096 bytes and must be power of two. Virtual device will announce this size as a minimal IO and logical sector. iv_large_sectors IV generators will use sector number counted in units instead of default 512 bytes sectors. WebSee cryptsetup-s. sector-size= Sector size. See cryptsetup(8) for possible values and the default value of this option. hash= Hash algorithm (ignored for LUKS and TCRYPT devices). See cryptsetup-h. offset= Start offset (ignored for LUKS and TCRYPT devices). Uses cryptsetup-o.
