Struct fog_crypto::identity::UnverifiedSignature

pub struct UnverifiedSignature { /* private fields */ }

A signature that has been read from a byte slice but hasn’t been verified yet.

Verification can be done by getting the appropriate version of hash into the verify(...) function.

Example

let data = b"I am some test data";
// ...

let unverified = UnverifiedSignature::try_from(&encoded[..])?;
let hash_version = unverified.hash_version();
let hash = Hash::with_version(&data[..], hash_version)?;
match unverified.verify(&hash) {
    Ok(verified) => {
        println!("Got valid signature, signed by {}", verified.signer());
    },
    Err(_) => {
        println!("Signature failed validation");
    }
}

Implementations

impl UnverifiedSignature

pub fn hash_version(&self) -> u8

Get the version of hash needed to complete the signature.

pub fn signer(&self) -> &Identity

The public Identity provided with this signature. Because this is an unverified signature, there can be no assurance that this identity has actually signed the data.

pub fn verify(self, hash: &Hash) -> Result<Signature, CryptoError>

Verify the Signature, producing a verified Signature or failing.

Trait Implementations

impl Clone for UnverifiedSignature

fn clone(&self) -> UnverifiedSignature

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for UnverifiedSignature

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

Formats the value using the given formatter.

impl PartialEq<UnverifiedSignature> for UnverifiedSignature

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl TryFrom<&[u8]> for UnverifiedSignature

type Error = CryptoError

The type returned in the event of a conversion error.

fn try_from(value: &[u8]) -> Result<Self, Self::Error>

Performs the conversion.
