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

Methods

impl<'a> Verifier<'a>

[−]

[−] Expand description

A type which verifies cryptographic signatures of data.

pub 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.

pub 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.

pub 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.

pub fn set_rsa_pss_saltlen(     &mut self,     len: RsaPssSaltlen ) -> Result<(), ErrorStack>

[−]

Sets the RSA PSS salt length.

This is only useful for RSA keys.

This corresponds to EVP_PKEY_CTX_set_rsa_pss_saltlen.

pub fn set_rsa_mgf1_md(&mut self, md: MessageDigest) -> Result<(), ErrorStack>

[−]

Sets the RSA MGF1 algorithm.

This is only useful for RSA keys.

This corresponds to EVP_PKEY_CTX_set_rsa_mgf1_md.

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.

Trait Implementations

impl<'a> Sync for Verifier<'a>

impl<'a> Send for Verifier<'a>

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<()>

[−]

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.
