Enum KeyExtension 

pub enum KeyExtension {
    None,
    Blumenthal,
}

Key extension strategy for privacy key derivation.

When using AES-192 or AES-256 with authentication protocols that produce shorter digests (e.g., SHA-1), a key extension algorithm is needed to generate sufficient key material.

Variants

None

No key extension. Requires compatible auth/priv protocol combinations. This is the default and will panic if insufficient key material.

Blumenthal

Use the Blumenthal key extension algorithm (draft-blumenthal-aes-usm-04). Extends keys by iteratively hashing: Kul’ = Kul || H(Kul) || H(Kul||H(Kul)) || …

Trait Implementations

impl Clone for KeyExtension

fn clone(&self) -> KeyExtension

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for KeyExtension

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

Formats the value using the given formatter.

impl Default for KeyExtension

fn default() -> KeyExtension

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for KeyExtension

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for KeyExtension

fn eq(&self, other: &KeyExtension) -> 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 KeyExtension

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
