Struct openssl::sign::Verifier

pub struct Verifier<'a> { /* fields omitted */ }

Methods

impl<'a> Verifier<'a>

A type which verifies cryptographic signatures of data.

pub fn new(
    type_: MessageDigest,
    pkey: &'a PKeyRef
) -> Result<Verifier<'a>, ErrorStack>

Creates a new Verifier.

OpenSSL documentation at EVP_DigestVerifyInit.

pub fn pkey_ctx(&self) -> &PKeyCtxRef

Returns a shared reference to the PKeyCtx associated with the Verifier.

pub fn pkey_ctx_mut(&mut self) -> &mut PKeyCtxRef

Returns a mutable reference to the PKeyCtx associated with the Verifier.

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

Feeds more data into the Verifier.

OpenSSL documentation at EVP_DigestUpdate.

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

Determines if the data fed into the Verifier matches the provided signature.

OpenSSL documentation at EVP_DigestVerifyFinal.

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

Deprecated since 0.9.23

: renamed to verify

Trait Implementations

impl<'a> Drop for Verifier<'a>

fn drop(&mut self)

Executes the destructor for this type.

impl<'a> Write for Verifier<'a>

fn write(&mut self, buf: &[u8]) -> Result<usize>

Write a buffer into this object, returning how many bytes were written.

fn flush(&mut self) -> Result<()>

Flush this output stream, ensuring that all intermediately buffered contents reach their destination.

fn write_all(&mut self, buf: &[u8]) -> Result<(), Error>

Attempts to write an entire buffer into this write.

fn write_fmt(&mut self, fmt: Arguments) -> Result<(), Error>

Writes a formatted string into this writer, returning any error encountered.

Important traits for &'a mut R

impl<'a, R> Read for &'a mut R where
    R: Read + ?Sized, impl<'a, W> Write for &'a mut W where
    W: Write + ?Sized, impl<'a, I> Iterator for &'a mut I where
    I: Iterator + ?Sized,  type Item = <I as Iterator>::Item;

fn by_ref(&mut self) -> &mut Self

Creates a "by reference" adaptor for this instance of Write.
