Struct Signature 

pub struct Signature;

structure contains serveral methods to handle signing of chunked data.

Implementations

impl Signature

pub fn new_keypair() -> Keypair

generates a new, random keypair.

pub fn new_keypair_from_base64<K: Into<String>>(key: K) -> Result<Keypair>

returns a keypair, parsed from the input data (formatted as base64).
Input data can be a secret key (32 bytes) or a secret/public keypair (64 bytes).

pub fn sign(keypair: &Keypair, message: &[u8]) -> [u8; 64]

sign the data with the given keypair bytes.

pub fn verify( publickey: [u8; 32], message: &[u8], signature: [u8; 64], ) -> Result<bool>

verify the data with the given public key bytes.

pub fn calculate_signature( signature_keypair: Option<&Keypair>, buffer: &[u8], ) -> Option<[u8; 64]>

calculates a signature of the given bytes with the given Keypair.
