Enum CryptographicKeyContext 

pub enum CryptographicKeyContext {
    OpenPgp {
        user_ids: OpenPgpUserIdList,
        version: OpenPgpVersion,
    },
    Raw,
}

The cryptographic context in which a key is used.

Variants

OpenPgp

A key is used in an OpenPGP context

Fields

user_ids: OpenPgpUserIdList

List of OpenPGP User IDs for the certificate.

version: OpenPgpVersion

OpenPGP version for the certificate.

Raw

A key is used in a raw cryptographic context

Implementations

impl CryptographicKeyContext

pub fn validate_signing_key_setup( &self, key_type: KeyType, key_mechanisms: &[KeyMechanism], signature_type: SignatureType, ) -> Result<(), Error>

Validates the cryptographic context against a signing key setup

Errors

Returns an error if the key setup can not be used for signing operations in the respective cryptographic context.

Examples

use signstar_crypto::key::{CryptographicKeyContext, KeyMechanism, KeyType, SignatureType};
use signstar_crypto::openpgp::{OpenPgpUserIdList, OpenPgpVersion};

CryptographicKeyContext::Raw.validate_signing_key_setup(
    KeyType::Curve25519,
    &[KeyMechanism::EdDsaSignature],
    SignatureType::EdDsa,
)?;

CryptographicKeyContext::OpenPgp {
    user_ids: OpenPgpUserIdList::new(vec!["Foobar McFooface <foobar@mcfooface.org>".parse()?])?,
    version: OpenPgpVersion::V4,
}
.validate_signing_key_setup(
    KeyType::Curve25519,
    &[KeyMechanism::EdDsaSignature],
    SignatureType::EdDsa,
)?;

Trait Implementations

impl Clone for CryptographicKeyContext

fn clone(&self) -> CryptographicKeyContext

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CryptographicKeyContext

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for CryptographicKeyContext

fn deserialize<__D>( __deserializer: __D, ) -> Result<CryptographicKeyContext, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for CryptographicKeyContext

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

Formats the value using the given formatter.

impl Hash for CryptographicKeyContext

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

where __H: Hasher,

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 CryptographicKeyContext

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<SignedPublicKey> for CryptographicKeyContext

fn try_from( value: SignedPublicKey, ) -> Result<CryptographicKeyContext, <CryptographicKeyContext as TryFrom<SignedPublicKey>>::Error>

Creates a CryptographicKeyContext from [SignedPublicKey].

Drops any invalid OpenPGP User ID (e.g. non-UTF-8).

Errors

Returns an error if

• duplicate OpenPGP User IDs are encountered in value,
• or no valid OpenPGP version can be derived from the OpenPGP primary key in value.

type Error = Error

The type returned in the event of a conversion error.
