Module crypto

Structs

CipherSuite

Wrapper type representing a ciphersuite identifier along with default values defined by the MLS RFC. Custom ciphersuites can be defined using a custom CryptoProvider.

HpkeCiphertext

Ciphertext produced by CipherSuiteProvider::hpke_seal

HpkePublicKey

Byte representation of an HPKE public key. For ciphersuites using elliptic curves, the public key should be represented in the uncompressed format.

HpkeSecretKey

Byte representation of an HPKE secret key.

SignaturePublicKey

Byte representation of a signature public key. For ciphersuites using elliptic curves, the public key should be represented in the uncompressed format.

SignatureSecretKey

Byte representation of a signature key.

Enums

HpkeModeId

Modes of HPKE operation.

Traits

CipherSuiteProvider

Provides all cryptographic operations required by MLS for a given cipher suite.

CryptoProvider

Provides implementations for several ciphersuites via CipherSuiteProvider.

HpkeContextR

The HPKE context for receiver outputted by hpke_setup_r. The context internally stores secrets received from the sender by hpke_setup_r.

HpkeContextS

The HPKE context for sender outputted by hpke_setup_s. The context internally stores the secrets generated by hpke_setup_s.
