Struct GenericVerifyingKey 

pub struct GenericVerifyingKey<D, T, M>
where
    D: Digest,
    T: UnsignedModularInt,
    M: ModulusParams<Modulus = T>,
{ /* private fields */ }

Verifying key for checking the validity of RSASSA-PSS signatures as described in RFC8017 § 8.1.

Implementations

impl<D, T, M> GenericVerifyingKey<D, T, M>

where D: Digest, T: UnsignedModularInt, M: ModulusParams<Modulus = T>,

pub fn new(key: GenericRsaPublicKey<T, M>) -> Self

Create a new RSASSA-PSS verifying key. Digest output size is used as a salt length.

pub fn new_with_salt_len( key: GenericRsaPublicKey<T, M>, salt_len: usize, ) -> Self

Create a new RSASSA-PSS verifying key.

pub fn new_with_auto_salt_len(key: GenericRsaPublicKey<T, M>) -> Self

Create a new RSASSA-PSS verifying key. Attempts to automatically detect the salt length.

pub fn salt_len(&self) -> Option<usize>

Return specified salt length for this key

Trait Implementations

impl<D, T, M> AsRef<GenericRsaPublicKey<T, M>> for GenericVerifyingKey<D, T, M>

where D: Digest, T: UnsignedModularInt, M: ModulusParams<Modulus = T>,

fn as_ref(&self) -> &GenericRsaPublicKey<T, M>

Converts this type into a shared reference of the (usually inferred) input type.

impl<D, T, M> Clone for GenericVerifyingKey<D, T, M>

where D: Digest, T: UnsignedModularInt, M: ModulusParams<Modulus = T> + Clone,

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<D, T, M> Debug for GenericVerifyingKey<D, T, M>

where D: Digest + Debug, T: UnsignedModularInt + Debug, M: ModulusParams<Modulus = T> + Debug,

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<D, T, M> DigestVerifier<D, GenericSignature<T>> for GenericVerifyingKey<D, T, M>

where D: Digest + FixedOutputReset + Update, T: UnsignedModularInt, M: ModulusParams<Modulus = T>,

fn verify_digest<F: Fn(&mut D) -> Result<()>>( &self, f: F, signature: &GenericSignature<T>, ) -> Result<()>

Verify the signature against the received Digest output, by updating it with the message.

impl<D, T, M> From<GenericRsaPublicKey<T, M>> for GenericVerifyingKey<D, T, M>

where D: Digest, T: UnsignedModularInt, M: ModulusParams<Modulus = T>,

fn from(key: GenericRsaPublicKey<T, M>) -> Self

Converts to this type from the input type.

impl<D, T, M> From<GenericVerifyingKey<D, T, M>> for GenericRsaPublicKey<T, M>

where D: Digest, T: UnsignedModularInt, M: ModulusParams<Modulus = T>,

fn from(key: GenericVerifyingKey<D, T, M>) -> Self

Converts to this type from the input type.

impl<D, T, M> PartialEq for GenericVerifyingKey<D, T, M>

where D: Digest, T: UnsignedModularInt + PartialEq, M: ModulusParams<Modulus = T>,

fn eq(&self, other: &Self) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<D, T, M> PrehashVerifier<GenericSignature<T>> for GenericVerifyingKey<D, T, M>

where D: Digest + FixedOutputReset, T: UnsignedModularInt, M: ModulusParams<Modulus = T>,

fn verify_prehash( &self, prehash: &[u8], signature: &GenericSignature<T>, ) -> Result<()>

Use Self to verify that the provided signature for a given message prehash is authentic.

impl<D, T, M> Verifier<GenericSignature<T>> for GenericVerifyingKey<D, T, M>

where D: Digest + FixedOutputReset, T: UnsignedModularInt, M: ModulusParams<Modulus = T>,

fn verify(&self, msg: &[u8], signature: &GenericSignature<T>) -> Result<()>

Use Self (e.g. a verifying key) to verify that the provided signature is authentic for a given message bytestring.
