Struct Verifier 

pub struct Verifier { /* private fields */ }

Streaming DigestVerify context.

Implementations

impl Verifier

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

Create a verifier.

Errors

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

Feed data into the hash.

Errors

pub fn verify(&mut self, signature: &[u8]) -> Result<bool, ErrorStack>

Verify signature against all data fed via update.

Returns Ok(true) if valid, Ok(false) if the signature is incorrect, or Err on a fatal OpenSSL error.

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

Errors

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

One-shot verify signature over data.

Required for algorithms that do not support streaming (Ed25519, Ed448).
