Enum KeyConsumer

Source 
pub enum KeyConsumer {
    Fxfs,
    Zxcrypt,
}
Expand description

Fxfs and zxcrypt have different null keys, so operations have to indicate which is ultimately going to consume the key we produce.

Variants§

§

Fxfs

The null key for fxfs is a 128-bit key with the bytes “zxcrypt” at the beginning and then padded with zeros. This is for legacy reasons - earlier versions of this code picked this key, so we need to continue to use it to avoid wiping everyone’s null-key-encrypted fxfs data partitions.

§

Zxcrypt

The null key for zxcrypt is a 256-bit key containing all zeros.
