Struct Signer 

pub struct Signer { /* private fields */ }

Streaming DigestSign context.

Call update zero or more times, then finish to produce the signature.

Implementations

impl Signer

pub fn new(key: &Pkey<Private>, init: &SignInit<'_>) -> Result<Self, ErrorStack>

Create a signer.

Errors

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

Feed data into the hash.

Errors

pub fn finish(&mut self) -> Result<Vec<u8>, ErrorStack>

Finalise and return the signature.

Not supported by pure one-shot algorithms such as Ed25519 — use sign_oneshot for those.

Errors

pub fn sign_oneshot(&mut self, data: &[u8]) -> Result<Vec<u8>, ErrorStack>

One-shot sign over data.

Required for algorithms that do not support streaming (Ed25519, Ed448). For algorithms that do support streaming, prefer update + finish.
