Struct tor_hsservice::internal_prelude::curve25519::StaticSecret

pub struct StaticSecret([u8; 32]);
Available on crate feature static_secrets only.
Expand description

A Diffie-Hellman secret key that can be used to compute multiple SharedSecrets.

This type is identical to the EphemeralSecret type, except that the StaticSecret::diffie_hellman method does not consume the secret key, and the type provides serialization methods to save and load key material. This means that the secret may be used multiple times (but does not have to be).

§Warning

If you’re uncertain about whether you should use this, then you likely should not be using this. Our strongly recommended advice is to use EphemeralSecret at all times, as that type enforces at compile-time that secret keys are never reused, which can have very serious security implications for many protocols.
