Trait PublicKeyEncryption 

pub trait PublicKeyEncryption {
    type PublicKey;
    type SecretKey;

    // Required methods
    fn keygen(bits: usize) -> (Self::PublicKey, Self::SecretKey);
    fn encrypt(pk: &Self::PublicKey, plaintext: &[u8]) -> Vec<u8> ;
    fn decrypt(sk: &Self::SecretKey, ciphertext: &[u8]) -> Option<Vec<u8>>;
}

Trait for public-key encryption schemes.

Like SignatureScheme, this trait is currently informational – the RSA encryption helpers in rsa::pkcs1 and rsa::oaep take a parameter of type rsa::rsa::RsaPublicKey / RsaSecretKey directly rather than going through this trait, because OAEP and PKCS#1 v1.5 each take additional protocol parameters (label, RNG) that don’t fit the simple shape below.

Required Associated Types

type PublicKey

Public key type.

type SecretKey

Secret key type.

Required Methods

fn keygen(bits: usize) -> (Self::PublicKey, Self::SecretKey)

Generate a key pair of the given bit size.

fn encrypt(pk: &Self::PublicKey, plaintext: &[u8]) -> Vec<u8>

Encrypt a plaintext under the public key.

fn decrypt(sk: &Self::SecretKey, ciphertext: &[u8]) -> Option<Vec<u8>>

Decrypt a ciphertext with the secret key. Returns None if the padding does not validate.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
