EchGrease

rama::tls::boring::client::ech

Enum EchGrease

pub enum EchGrease {
    Native,
    Shape {
        kdf_id: u16,
        aead_id: u16,
        encapsulated_key_len: usize,
        payload_len: usize,
    },
}

Available on crate feature boring only.

Expand description

Shape of an ECH GREASE extension, applied independently of its enable switch.

Invalid shapes are rejected when building the connector, before it writes a ClientHello. TLS 1.3 and super::BoringClientConfigExt::set_encrypted_client_hello must also be enabled. A usable real ECH configuration takes precedence.

Variants§

Native

Use the provider’s randomized lengths and hardware-dependent algorithms. Explicitly selecting this also overrides a shape inherited from a base config.

Shape

Reproduce retained ECH outer metadata using fresh encapsulation and payload.

Fields

§kdf_id: u16

HPKE KDF identifier; the provider currently supports HKDF-SHA256 (1).

§aead_id: u16

HPKE AEAD identifier: AES-128-GCM (1), AES-256-GCM (2) or ChaCha20-Poly1305 (3).

§encapsulated_key_len: usize

Encapsulated key length in bytes; X25519 requires 32.

§payload_len: usize

Encrypted payload length in bytes, including the authentication tag.
