Struct HookGeometry 

Source 
pub struct HookGeometry {
    pub partition_guid: Guid,
    pub offset_sector: u64,
    pub encrypted_offset: EncryptedOffset,
}
Expand description

Geometry the Block IO decrypt hook needs to map an absolute LBA to a data-region-relative sector and decide whether it is ciphertext. The cipher itself is supplied separately (the sample builds it), so no key material lives here.

Fields§

§partition_guid: Guid

GPT unique partition GUID of the volume whose Block IO is hooked.

§offset_sector: u64

Absolute starting LBA of the data (encryption target) region. The hooked read computes rel = lba - offset_sector from this value.

§encrypted_offset: EncryptedOffset

Progressive-encryption boundary and total data-region sector count.
