Struct StaticCipherSupplier 

pub struct StaticCipherSupplier { /* private fields */ }

Default VolumeCipherSupplier for volumes that store AES-256-XTS key material in ordinary (non-protected) memory.

Reconstructs the AES key schedule on each get_cipher call. The cost is one AES key expansion (~480 bytes of computation) per I/O burst — negligible compared with the I/O itself and bounded to once per [MAX_IRP_BURST] IRPs.

For RAM-encryption, implement VolumeCipherSupplier directly: derive the key from protected storage on each call and override VolumeCipher::destroy to zeroize it.

Implementations

impl StaticCipherSupplier

pub fn new(key1: [u8; 32], key2: [u8; 32]) -> Self

Trait Implementations

impl VolumeCipherSupplier for StaticCipherSupplier

fn get_cipher(&self) -> Option<Box<dyn VolumeCipher>>

Acquire a cipher for one I/O burst or sweep batch.
