Struct safe_crypto::PublicEncryptKey

pub struct PublicEncryptKey { /* fields omitted */ }

The public key used encrypt data that can only be decrypted by the corresponding secret key, which is represented by SecretEncryptKey. Use gen_encrypt_keypair() to generate a public and secret key pair.

Methods

impl PublicEncryptKey

pub fn from_bytes(public_key: [u8; 32]) -> Self

Construct public key from bytes. Useful when it was serialised before.

pub fn into_bytes(self) -> [u8; 32]

Convert the PublicEncryptKey into the raw underlying bytes. For anyone who wants to store the public key.

pub fn anonymously_encrypt<T>(&self, plaintext: &T) -> Result<Vec<u8>, Error> where     T: Serialize,

Encrypts serialisable plaintext using anonymous encryption.

Anonymous encryption will use an ephemeral public key, so the recipient won't be able to tell who sent the ciphertext. If you wish to encrypt bytestring plaintext, use anonymously_encrypt_bytes. To use authenticated encryption, use SharedSecretKey.

Returns ciphertext in case of success. Can return an Error in case of a serialisation error.

pub fn anonymously_encrypt_bytes(&self, plaintext: &[u8]) -> Vec<u8>

Encrypts bytestring plaintext using anonymous encryption.

Anonymous encryption will use an ephemeral public key, so the recipient won't be able to tell who sent the ciphertext. To use authenticated encryption, use SharedSecretKey.

Returns ciphertext in case of success.
