Struct FxfsKey 

pub struct FxfsKey {
    pub wrapping_key_id: WrappingKeyId,
    pub key: WrappedKeyBytes,
}

An Fxfs encryption key wrapped in AES-256-GCM-SIV and the associated wrapping key ID. This can be provided to Crypt::unwrap_key to obtain the unwrapped key.

Fields

wrapping_key_id: WrappingKeyId

The identifier of the wrapping key. The identifier has meaning to whatever is doing the unwrapping.

key: WrappedKeyBytes

AES 256 requires a 512 bit key, which is made of two 256 bit keys, one for the data and one for the tweak. It is safe to use the same 256 bit key for both (see https://csrc.nist.gov/CSRC/media/Projects/Block-Cipher-Techniques/documents/BCM/Comments/XTS/follow-up_XTS_comments-Ball.pdf) which is what we do here. Since the key is wrapped with AES-GCM-SIV, there are an additional 16 bytes paid per key (so the actual key material is 32 bytes once unwrapped).

Trait Implementations

impl<'a> Arbitrary<'a> for FxfsKey

fn arbitrary(_u: &mut Unstructured<'a>) -> Result<Self>

Generate an arbitrary value of Self from the given unstructured data.

fn arbitrary_take_rest(u: Unstructured<'a>) -> Result<Self, Error>

Generate an arbitrary value of Self from the entirety of the given unstructured data.

fn size_hint(depth: usize) -> (usize, Option<usize>)

Get a size hint for how many bytes out of an Unstructured this type needs to construct itself.

impl Clone for FxfsKey

fn clone(&self) -> FxfsKey

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for FxfsKey

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for FxfsKey

fn default() -> FxfsKey

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for FxfsKey

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<FxfsKey> for FxfsKey

fn from(value: FxfsKey) -> Self

Converts to this type from the input type.

impl PartialEq for FxfsKey

fn eq(&self, other: &FxfsKey) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for FxfsKey

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TypeFingerprint for FxfsKey

fn fingerprint() -> String
