Struct DsaPublicKey 

pub struct DsaPublicKey { /* private fields */ }

Public key for DSA.

Implementations

impl DsaPublicKey

pub fn modulus(&self) -> &BigUint

Return the prime modulus.

pub fn subgroup_order(&self) -> &BigUint

Return the prime subgroup order.

pub fn generator(&self) -> &BigUint

Return the subgroup generator.

pub fn public_component(&self) -> &BigUint

Return the public component y = g^x mod p.

pub fn verify_message<H: Digest>( &self, message: &[u8], signature: &DsaSignature, ) -> bool

Hash one message with H, then verify the resulting digest.

pub fn verify_message_bytes<H: Digest>( &self, message: &[u8], signature: &[u8], ) -> bool

Hash one message with H, then verify a serialized signature.

pub fn verify_digest_scalar( &self, hash: &BigUint, signature: &DsaSignature, ) -> bool

Verify a signature over an explicit integer representative.

pub fn verify(&self, digest: &[u8], signature: &DsaSignature) -> bool

Verify a signature over the provided digest bytes.

The digest is reduced to the leftmost N = bits(q) bits, matching the DSA representative construction from the Digital Signature Standard.

pub fn verify_bytes(&self, digest: &[u8], signature: &[u8]) -> bool

Verify a byte-encoded signature produced by [DsaPrivateKey::sign_bytes].

pub fn to_key_blob(&self) -> Vec<u8>

Encode the public key in the crate-defined binary format.

pub fn from_key_blob(blob: &[u8]) -> Option<Self>

Decode the public key from the crate-defined binary format.

pub fn to_pem(&self) -> String

Encode the public key in PEM using the crate-defined label.

pub fn to_xml(&self) -> String

Encode the public key as the crate’s flat XML form.

pub fn from_pem(pem: &str) -> Option<Self>

Decode the public key from the crate-defined PEM label.

pub fn from_xml(xml: &str) -> Option<Self>

Decode the public key from the crate’s flat XML form.

Trait Implementations

impl Clone for DsaPublicKey

fn clone(&self) -> DsaPublicKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DsaPublicKey

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

Formats the value using the given formatter.

impl PartialEq for DsaPublicKey

fn eq(&self, other: &DsaPublicKey) -> 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.
