Implementations

impl KeyExchangeGroup

pub const fn to_wire(self) -> [u8; 2]

TLS wire identifier (two bytes, big-endian).

pub const fn from_wire(bytes: [u8; 2]) -> Option<Self>

Parse a key exchange group from its wire identifier.

pub const fn public_key_size_client(self) -> usize

Size of the client-side KeyShare entry for this group, in bytes.

pub const fn public_key_size_server(self) -> usize

Size of the server-side KeyShare entry for this group, in bytes.

For KEM-based groups the server returns a ciphertext (which may differ from the client’s public key size).
