Struct exonum_crypto::PublicKey

pub struct PublicKey(_);

Ed25519 public key used to verify digital signatures.

In public-key cryptography, the system uses a a mathematically related pair of keys: a public key, which is openly distributed, and a secret key, which should remain confidential. For more information, refer to Public-key cryptography.

Ed25519 is a signature system that ensures fast signing and key generation, as well as security and collision resilience.

Examples

In the example below, the function generates a pair of random public and secret keys.

let (public_key, _) = exonum_crypto::gen_keypair();
