Enum KeyIdMethod

#[non_exhaustive]
pub enum KeyIdMethod {
    Sha256,
    Sha384,
    Sha512,
    PreSpecified(Vec<u8>),
}

Method to generate key identifiers from public keys.

Key identifiers should be derived from the public key data. RFC 7093 defines three methods to do so using a choice of SHA256 (method 1), SHA384 (method 2), or SHA512 (method 3). In each case the first 160 bits of the hash are used as the key identifier to match the output length that would be produced were SHA1 used (a legacy option defined in RFC 5280).

In addition to the RFC 7093 mechanisms, rcgen supports using a pre-specified key identifier. This can be helpful when working with an existing Certificate.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Sha256

RFC 7093 method 1 - a truncated SHA256 digest.

Sha384

RFC 7093 method 2 - a truncated SHA384 digest.

Sha512

RFC 7093 method 3 - a truncated SHA512 digest.

PreSpecified(Vec<u8>)

Pre-specified identifier. The exact given value is used as the key identifier.

Trait Implementations

impl Clone for KeyIdMethod

fn clone(&self) -> KeyIdMethod

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for KeyIdMethod

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

Formats the value using the given formatter.

impl Hash for KeyIdMethod

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 KeyIdMethod

fn eq(&self, other: &KeyIdMethod) -> 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.
