Trait for ECIES stream cipher.

The EciesStream trait provides methods for creating encryptors and decryptors that work with streams of data.

Type Parameters

• PrivateKey: the type representing a private key.
• PublicKey: the type representing a public key.
• RustCryptoBackend: the RustCrypto symmetric cryptographic backend used to perform operations.

Required Methods

fn get_dem_encryptor_be32<R: CryptoRngCore>( rng: &mut R, recipient_public_key: &PublicKey, ) -> Result<(PublicKey, EncryptorBE32<RustCryptoBackend>), CryptoCoreError>

Creates a EncryptorBE32 using the given public key.

fn get_dem_encryptor_le31<R: CryptoRngCore>( rng: &mut R, recipient_public_key: &PublicKey, ) -> Result<(PublicKey, EncryptorLE31<RustCryptoBackend>), CryptoCoreError>

Creates a EncryptorLE31 using the given public key.

fn get_dem_decryptor_be32( recipient_private_key: &PublicKey::PrivateKey, ephemeral_public_key: &PublicKey, ) -> Result<DecryptorBE32<RustCryptoBackend>, CryptoCoreError>

Creates a DecryptorBE32 using the given private key.

fn get_dem_decryptor_le31( recipient_private_key: &PublicKey::PrivateKey, ephemeral_public_key: &PublicKey, ) -> Result<DecryptorLE31<RustCryptoBackend>, CryptoCoreError>

Creates a DecryptorLE31 using the given private key.

Object Safety

This trait is not object safe.
