Struct openssl::sign::Verifier

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

Methods

impl<'a> Verifier<'a>

A type which verifies cryptographic signatures of data.

fn new<T>(
    type_: MessageDigest,
    pkey: &'a PKeyRef<T>
) -> Result<Verifier<'a>, ErrorStack> where
    T: HasPublic, 

Creates a new Verifier.

OpenSSL documentation at EVP_DigestVerifyInit.

fn rsa_padding(&self) -> Result<Padding, ErrorStack>

Returns the RSA padding mode in use.

This is only useful for RSA keys.

This corresponds to EVP_PKEY_CTX_get_rsa_padding.

fn set_rsa_padding(&mut self, padding: Padding) -> Result<(), ErrorStack>

Sets the RSA padding mode.

This is only useful for RSA keys.

This corresponds to EVP_PKEY_CTX_set_rsa_padding.

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

Feeds more data into the Verifier.

OpenSSL documentation at EVP_DigestUpdate.

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.

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.

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

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