}

Trait implemented by signature plugins. The type Self serves as both the signer and verifier state — the plugin dispatches internally based on which entry points are called.

Required Methods

fn signer_create( algorithm: &str, secret_key: &[u8], opts: Option<OptionView<'_>>, ) -> PluginResult<Self>

Construct a signer from the secret key.

fn verifier_create( algorithm: &str, public_key: &[u8], opts: Option<OptionView<'_>>, ) -> PluginResult<Self>

Construct a verifier from the public key.

fn set_hash(&mut self, hash_name: &str) -> PluginResult<()>

Set the hash algorithm used for signing/verifying (for hash-then-sign schemes).

fn update(&mut self, data: &[u8]) -> PluginResult<()>

Absorb message bytes into the signing/verification context.

fn signer_finalize(&mut self, sig_out: &mut [u8]) -> PluginResult<usize>

Finalize signing: write the signature into sig_out. Returns the number of bytes written.

fn verifier_finalize(&mut self, signature: &[u8]) -> PluginResult<()>

Finalize verification: return Ok(()) if the signature is valid.

fn keypair_generate( algorithm: &str, seed: Option<&[u8]>, opts: Option<OptionView<'_>>, ) -> PluginResult<SignatureKeypair>

Generate a keypair for the named algorithm. If seed is provided, it is used deterministically; otherwise the plugin generates fresh randomness.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
