Struct Config 

pub struct Config {
    pub aead: Aead,
    pub kdf: Kdf,
    pub kem: Kem,
}

Configuration for crate interfaces.

Contains an (Aead, Kdf, Kem) algorithmic triple. This can be used with Config::base_mode_seal, Config::base_mode_open, base_mode_seal, or base_mode_open.

Fields

aead: Aead

the authenticated encryption with additional data encryption function to be used

kdf: Kdf

the key derivation function to be used

kem: Kem

the asymmetric key encapsulation mechanism to be used

Implementations

impl Config

pub fn base_mode_seal( &self, recipient_public_key: &[u8], info: &[u8], plaintext: &[u8], aad: &[u8], ) -> Result<EncappedKeyAndCiphertext, HpkeError>

Single-shot HPKE ciphertext sealing.

base_mode_seal provides an interface to hpke::single_shot_seal that does not require compile time selection of an algorithm. Instead, the selected algorithm is provided through the receiver.

Errors

This will return a Result::Err variant if:

• we are unable to deserialize the recipient public key
• there is an error in key encapsultion
• there is an error in encryption

pub fn base_mode_open( &self, private_key: &[u8], encapped_key: &[u8], info: &[u8], ciphertext: &[u8], aad: &[u8], ) -> Result<Vec<u8>, HpkeError>

Single-shot HPKE ciphertext opening.

base_mode_open provides an interface to hpke::single_shot_open that does not require compile time selection of an algorithm. Instead, the selected algorithm is provided through the receiver

Errors

This will return a Result::Err variant if:

• we are unable to deserialize the private key or encapsulated key
• there is an error in key decapsulation
• there is an error in decryption

pub fn try_from_ids( aead_id: u16, kdf_id: u16, kem_id: u16, ) -> Result<Config, IdLookupError>

Attempt to convert three u16 ids into a valid Config.

The ID mappings are defined in the IANA HPKE registries.
