pub trait Signer<S>where
    S: Signature,
{ fn try_sign(&self, msg: &[u8]) -> Result<S, Error>; fn sign(&self, msg: &[u8]) -> S { ... } }
Expand description

Sign the provided message bytestring using Self (e.g. a cryptographic key or connection to an HSM), returning a digital signature.

Required Methods

Attempt to sign the given message, returning a digital signature on success, or an error if something went wrong.

The main intended use case for signing errors is when communicating with external signers, e.g. cloud KMS, HSMs, or other hardware tokens.

Provided Methods

Sign the given message and return a digital signature
