Struct SigningKey 

pub struct SigningKey(/* private fields */);

A signature.signing-key: private-key signing.

Implementations

impl SigningKey

pub fn from_raw(raw: SigningKey) -> Self

Wrap a raw signing-key resource.

pub fn as_raw(&self) -> &SigningKey

Borrow the raw signing-key resource.

pub fn into_raw(self) -> SigningKey

Unwrap into the raw signing-key resource.

impl SigningKey

pub async fn sign( &self, data: impl Into<DataSource<'_>>, ) -> Result<Vec<u8>, Error>

Sign data, returning the signature in the minting interface’s documented wire format.

Fails only for operational reasons (Error::Other, or Error::Read for a failing DataSource::from_reader source) — never for misuse, which is unrepresentable.

pub fn algorithm_name(&self) -> String

See VerifyingKey::algorithm_name.

pub fn algorithm_curve(&self) -> Option<String>

See VerifyingKey::algorithm_curve.

pub fn algorithm_hash(&self) -> Option<String>

See VerifyingKey::algorithm_hash.

pub fn algorithm_length(&self) -> Option<u32>

See VerifyingKey::algorithm_length.

pub fn algorithm_public_exponent(&self) -> Option<Vec<u8>>

See VerifyingKey::algorithm_public_exponent.

pub fn extractable(&self) -> bool

Whether the private key material may be exported. There is currently no export operation — extractability is mint-time recorded policy that future format-specific exports and platform-backed key storage honor (see the WIT signing-key.extractable doc).

pub fn can_sign(&self) -> bool

Whether the key permits sign — the usage recorded at mint (or carried by a platform keystore key). A refused operation fails Error::NotPermitted.

Trait Implementations

impl Debug for SigningKey

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

Formats the value using the given formatter.

impl From<SigningKey> for SigningKey

fn from(raw: SigningKey) -> Self

Converts to this type from the input type.
