Trait jwt_compact::alg::SigningKey

pub trait SigningKey<T>: Sized where
    T: Algorithm<SigningKey = Self>, {
    fn from_slice(raw: &[u8]) -> Result<Self>;
    fn to_verifying_key(&self) -> T::VerifyingKey;
    fn as_bytes(&self) -> SecretBytes<'_>;
}

Signing key for a specific signature cryptosystem. In the case of public-key cryptosystems, this is a private key.

This trait provides a uniform interface for different backends / implementations of the same cryptosystem.

Required methods

fn from_slice(raw: &[u8]) -> Result<Self>

Creates a key from raw bytes. Returns an error if the bytes do not represent a valid key.

fn to_verifying_key(&self) -> T::VerifyingKey

Converts a signing key to a verification key.

fn as_bytes(&self) -> SecretBytes<'_>

Returns the key as raw bytes.

Implementations should return Cow::Borrowed whenever possible (that is, if the bytes are actually stored within the implementing data structure).

Implementations on Foreign Types

impl SigningKey<Es256k<CoreWrapper<CtVariableCoreWrapper<Sha256VarCore, UInt<UInt<UInt<UInt<UInt<UInt<UTerm, B1>, B0>, B0>, B0>, B0>, B0>>>>> for SecretKey

This implementation initializes a libsecp256k1 context once on the first call to to_verifying_key if it was not initialized previously.
