AddressTokenKey

rama::quic

Struct AddressTokenKey 

pub struct AddressTokenKey(/* private fields */);
Available on crate feature quic and crate feature std and (crate features aws-lc or ring) only.
Expand description

The key a server seals address-validation tokens with (RFC 9000 §8.1).

Retry tokens and the tokens sent in NEW_TOKEN frames are sealed with it, so servers holding the same key can read one another’s, as can a server that keeps its key across a restart. Reading a token is not accepting it: the address it was issued for, its lifetime and, for a NEW_TOKEN token, whether it has been seen before all still decide. A server given no key generates one. The same secrecy applies as for StatelessResetKey.

The material is derived with HKDF-SHA256 whichever provider is compiled in.

Implementations§

§

impl AddressTokenKey

pub fn from_seed(seed: &[u8; 32]) -> AddressTokenKey

Construct a key from a seed of KEY_MATERIAL_SIZE bytes.

pub fn try_from_bytes(material: &[u8]) -> Result<AddressTokenKey, ConfigError>

Construct a key from at least KEY_MATERIAL_SIZE bytes of secret material.

Fails when the material is shorter than that.
