Struct StaticKeypair 

pub struct StaticKeypair { /* private fields */ }

Available on crate feature crypto only.

A static X25519 keypair for long-term identity.

The private key is zeroized on drop for security.

Implementations

impl StaticKeypair

pub fn generate() -> Self

Generate a new random keypair.

pub fn from_bytes(private: [u8; 32], public: [u8; 32]) -> Self

Create a keypair from existing key material.

Safety

The caller must ensure the private key is valid X25519 key material.

pub fn public_key(&self) -> &[u8; 32]

Get the public key.

pub fn private_key(&self) -> &[u8; 32]

Get the private key.

Security

Handle with care - this exposes sensitive key material.

pub fn compute_static_dh(&self, remote_public: &[u8; 32]) -> [u8; 32]

Compute the static DH shared secret with a remote public key.

This computes DH(our_static, their_static) which is used for deriving the rekey authentication key for PCS.

Arguments

• remote_public - The remote party’s static public key

Returns

The 32-byte shared secret
