Enum KeyPurpose 

pub enum KeyPurpose {
    Signing,
    Verification,
    Encryption,
    Decryption,
    KeyExchange,
    Authentication,
    Derivation,
    Hashing,
}

Key purposes for search filtering.

A key’s purpose describes the cryptographic role it is intended for (signing, encryption, key exchange, etc.). This is orthogonal to the raw KeyAlgorithm — e.g. an AES key may be used for either Encryption or Decryption.

Variants

Signing

Digital signature generation

Verification

Signature verification

Encryption

Data encryption

Decryption

Data decryption

KeyExchange

Key exchange / key agreement

Authentication

Authentication / identity proof

Derivation

Key derivation

Hashing

Hashing / fingerprinting

Trait Implementations

impl Clone for KeyPurpose

fn clone(&self) -> KeyPurpose

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for KeyPurpose

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for KeyPurpose

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for KeyPurpose

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for KeyPurpose

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for KeyPurpose

impl StructuralPartialEq for KeyPurpose
