Struct Signature

pub struct Signature { /* private fields */ }

A versionned signature. Can be used to validate if some data has been tampered.

Implementations

impl Signature

pub fn verify(&self, data: &[u8], public_key: &SigningPublicKey) -> bool

Verify if the signature matches with the specified data and key.

Arguments

• data - The data that’s signed.
• public_key - The public part of the keypair used to sign the data.

Returns

Returns true if the signature is valid and false if it doesn’t.

Example

use devolutions_crypto::signing_key::{generate_signing_keypair, SigningKeyVersion, SigningKeyPair};
use devolutions_crypto::signature::{sign, Signature, SignatureVersion};

let keypair: SigningKeyPair = generate_signing_keypair(SigningKeyVersion::Latest);
let signature: Signature = sign(b"this is some test data", &keypair, SignatureVersion::Latest);

assert!(signature.verify(b"this is some test data", &keypair.get_public_key()));

Trait Implementations

impl Clone for Signature

fn clone(&self) -> Signature

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Signature

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

Formats the value using the given formatter.

impl From<Signature> for Vec<u8>

fn from(data: Signature) -> Self

Serialize the structure into a Vec<u8>, for storage, transmission or use in another language.

impl HeaderType for Signature

type Version = SignatureVersion

type Subtype = SignatureSubtype

fn data_type() -> DataType

fn default_version() -> Self::Version

fn subtype() -> Self::Subtype

impl TryFrom<&[u8]> for Signature

fn try_from(data: &[u8]) -> Result<Self>

Parses the data. Can return an Error of the data is invalid or unrecognized.

type Error = Error

The type returned in the event of a conversion error.
