Struct SignatureContext 

pub struct SignatureContext { /* private fields */ }

Signature context for digital signature operations

Implementations

impl SignatureContext

pub fn new() -> SignatureContext

Create a new signature context with no provider

pub fn with_provider(provider: Box<dyn CryptoProvider>) -> SignatureContext

Create a new signature context with a provider

pub fn with_default_provider() -> SignatureContext

Create a new signature context with the default provider

pub fn set_provider(&mut self, provider: Box<dyn CryptoProvider>)

Set the cryptographic provider

pub fn provider(&self) -> Option<&dyn CryptoProvider>

Get the current provider

pub fn generate_keypair( &mut self, algorithm: Algorithm, randomness: Option<&[u8]>, ) -> Result<SigKeypair, Error>

Generate a keypair for the specified algorithm

pub fn sign( &self, algorithm: Algorithm, secret_key: &SigSecretKey, message: &[u8], randomness: Option<&[u8]>, ) -> Result<Vec<u8>, Error>

Sign a message using the given secret key

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

Verify a signature for the given message and public key

pub fn is_initialized(&self) -> bool

Check if the context is initialized
