pub struct Verifier<'a> { /* private fields */ }
Expand description
A type which can be used to verify the integrity and authenticity of data given the signature.
Implementations§
source§impl<'a> Verifier<'a>
impl<'a> Verifier<'a>
A type which verifies cryptographic signatures of data.
sourcepub fn new<T>(
type_: MessageDigest,
pkey: &'a PKeyRef<T>,
) -> Result<Verifier<'a>, ErrorStack>where
T: HasPublic,
pub fn new<T>(
type_: MessageDigest,
pkey: &'a PKeyRef<T>,
) -> Result<Verifier<'a>, ErrorStack>where
T: HasPublic,
Creates a new Verifier
.
This cannot be used with Ed25519 or Ed448 keys. Please refer to
Verifier::new_without_digest
.
This corresponds to EVP_DigestVerifyInit
.
sourcepub fn new_without_digest<T>(
pkey: &'a PKeyRef<T>,
) -> Result<Verifier<'a>, ErrorStack>where
T: HasPublic,
pub fn new_without_digest<T>(
pkey: &'a PKeyRef<T>,
) -> Result<Verifier<'a>, ErrorStack>where
T: HasPublic,
Creates a new Verifier
without a digest.
This is the only way to create a Verifier
for Ed25519 or Ed448 keys.
This corresponds to EVP_DigestVerifyInit
.
sourcepub fn rsa_padding(&self) -> Result<Padding, ErrorStack>
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
.
sourcepub fn set_rsa_padding(&mut self, padding: Padding) -> Result<(), ErrorStack>
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
.
sourcepub fn set_rsa_pss_saltlen(
&mut self,
len: RsaPssSaltlen,
) -> Result<(), ErrorStack>
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
.
sourcepub fn set_rsa_mgf1_md(&mut self, md: MessageDigest) -> Result<(), ErrorStack>
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
.
sourcepub fn update(&mut self, buf: &[u8]) -> Result<(), ErrorStack>
pub fn update(&mut self, buf: &[u8]) -> Result<(), ErrorStack>
Feeds more data into the Verifier
.
Please note that PureEdDSA (Ed25519 and Ed448 keys) do not support streaming.
Use Verifier::verify_oneshot
instead.
This corresponds to EVP_DigestUpdate
.
sourcepub fn verify(&self, signature: &[u8]) -> Result<bool, ErrorStack>
pub fn verify(&self, signature: &[u8]) -> Result<bool, ErrorStack>
Determines if the data fed into the Verifier
matches the provided signature.
This corresponds to EVP_DigestVerifyFinal
.
sourcepub fn verify_oneshot(
&mut self,
signature: &[u8],
buf: &[u8],
) -> Result<bool, ErrorStack>
pub fn verify_oneshot( &mut self, signature: &[u8], buf: &[u8], ) -> Result<bool, ErrorStack>
Determines if the data given in buf
matches the provided signature.
This corresponds to EVP_DigestVerify
.
