Struct Verifier 

pub struct Verifier { /* private fields */ }

Verifier for verifying signatures for a message using a public key.

This verifier can be configured to allow_malleable mode, which allows verifying signatures with “high-S” or DER-encoded ones. By default, this verifier allows only “low-S” signatures.

Implementations

impl Verifier

pub fn new(allow_malleable: bool) -> Self

Create a new verifier with the given malleable mode.

pub fn verify( &self, algorithm: Algorithm, public_key: &[u8], msg: &[u8], signature: &[u8], ) -> Result<()>

Verify a signature for a message using the given public key. The algorithm is used to determine the curve for the public key.

pub fn verify_inner<C>( &self, public_key: &[u8], msg: &[u8], bytes: &[u8], ) -> Result<()>

where C: PrimeCurve + CurveArithmetic + DigestPrimitive, AffinePoint<C>: VerifyPrimitive<C> + FromEncodedPoint<C> + ToEncodedPoint<C>, FieldBytesSize<C>: ModulusSize, SignatureSize<C>: ArrayLength<u8>, MaxSize<C>: ArrayLength<u8>, <FieldBytesSize<C> as Add>::Output: Add<MaxOverhead> + ArrayLength<u8>,

Verify a signature for a message using the given public key. Any elliptic curve of the generics implementation of ECDSA can be used for parameter C.

Trait Implementations

impl Debug for Verifier

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

Formats the value using the given formatter.

impl Default for Verifier

fn default() -> Verifier

Returns the “default value” for a type.
