[][src]Struct openssl::sign::Verifier

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

Methods

impl<'a> Verifier<'a>[src]

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
[src]

Creates a new Verifier.

This cannot be used with Ed25519 or Ed448 keys. Please refer to new_without_digest.

OpenSSL documentation at EVP_DigestVerifyInit.

pub fn new_without_digest<T>(
    pkey: &'a PKeyRef<T>
) -> Result<Verifier<'a>, ErrorStack> where
    T: HasPublic
[src]

Creates a new Verifier without a digest.

This is the only way to create a Verifier for Ed25519 or Ed448 keys.

OpenSSL documentation at EVP_DigestVerifyInit.

pub fn rsa_padding(&self) -> Result<Padding, ErrorStack>[src]

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>[src]

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>
[src]

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>[src]

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>[src]

Feeds more data into the Verifier.

Please note that PureEdDSA (Ed25519 and Ed448 keys) do not support streaming. Use verify_oneshot instead.

OpenSSL documentation at EVP_DigestUpdate.

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

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

OpenSSL documentation at EVP_DigestVerifyFinal.

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

Determines if the data given in buf matches the provided signature.

OpenSSL documentation at EVP_DigestVerify.
