Struct tuf::crypto::KeyId

pub struct KeyId(_);

Wrapper type for public key's ID.

Calculating

In order to future proof the calculation of key IDs and preserver them across encoding types, a key's ID is calculated as the Sha-256 hash of the DER bytes of a key in Subject Public Key Info (SPKI) format.

SEQUENCE {
  SEQUENCE {
    OBJECT IDENTIFIER
    NULL
  }
  BIT STTRING
}

Where BIT STRING encapsulates the actual public key. In the case of RSA this is:

SEQUENCE {
  INTEGER (n, modulus)
  INTEGER (e, exponent)
}

Methods

impl KeyId

fn from_string(string: &str) -> Result<Self>

Parse a key ID from a base64url string.

Trait Implementations

impl Clone for KeyId

fn clone(&self) -> KeyId

Returns a copy of the value.

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

Performs copy-assignment from source.

impl PartialEq for KeyId

fn eq(&self, __arg_0: &KeyId) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, __arg_0: &KeyId) -> bool

This method tests for !=.

impl Eq for KeyId

impl Hash for KeyId

fn hash<__H: Hasher>(&self, __arg_0: &mut __H)

Feeds this value into the given [Hasher].

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

Feeds a slice of this type into the given [Hasher].

impl PartialOrd for KeyId

fn partial_cmp(&self, __arg_0: &KeyId) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, __arg_0: &KeyId) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, __arg_0: &KeyId) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, __arg_0: &KeyId) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, __arg_0: &KeyId) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl Ord for KeyId

fn cmp(&self, __arg_0: &KeyId) -> Ordering

This method returns an Ordering between self and other.

impl Debug for KeyId

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

fn serialize<S>(&self, ser: S) -> Result<S::Ok, S::Error> where
    S: Serializer, 

Serialize this value into the given Serde serializer.

impl<'de> Deserialize<'de> for KeyId
