This source reference follows declared modules and preserves feature attributes. It includes public declarations and implementation methods in those modules. Private-module exports and trait resolution still require the compiler; not every declaration is a crate-root import. Function bodies and constant values are omitted. Source comments describe their implementation context and are not a production deployment claim.

x25519::SECRET_KEY_LEN

Length of an X25519 secret (private) key in bytes.

pub const SECRET_KEY_LEN: usize;

Source line: 15.

x25519::PUBLIC_KEY_LEN

Length of an X25519 public key in bytes.

pub const PUBLIC_KEY_LEN: usize;

Source line: 17.

x25519::SHARED_SECRET_LEN

Length of an X25519 raw shared secret in bytes.

pub const SHARED_SECRET_LEN: usize;

Source line: 19.

x25519::X25519Keypair

An X25519 keypair (Curve25519, RFC 7748).

The secret key is zeroized on drop.

pub struct X25519Keypair {

}

Source line: 24.

x25519::X25519Keypair::secret_key_bytes

Returns a copy of the 32-byte secret key bytes.

#[inline]
pub fn secret_key_bytes(&self) -> [u8; SECRET_KEY_LEN];

Source line: 47.

x25519::X25519Keypair::public_key_bytes

Returns a copy of the 32-byte public key bytes.

#[inline]
pub fn public_key_bytes(&self) -> [u8; PUBLIC_KEY_LEN];

Source line: 53.

x25519::generate_keypair

Generates a fresh X25519 keypair using the OS / WASM host CSPRNG.

pub fn generate_keypair() -> X25519Keypair;

Source line: 59.

x25519::public_from_secret

Derives an X25519 public key from a 32-byte secret key.

Errors

[CryptoError::InvalidLength] if secret_key is not exactly 32 bytes.

pub fn public_from_secret(secret_key: &[u8]) -> Result<[u8; PUBLIC_KEY_LEN], CryptoError>;

Source line: 77.

x25519::diffie_hellman

Performs an X25519 Diffie-Hellman key exchange.

Returns the raw 32-byte shared secret. Callers MUST process this through a KDF (e.g. [crate::hkdf_sha256]) before using it as keying material.

Errors

[CryptoError::InvalidLength] if either input is not 32 bytes.

pub fn diffie_hellman(
    secret_key: &[u8],
    peer_public_key: &[u8],
) -> Result<[u8; SHARED_SECRET_LEN], CryptoError>;

Source line: 94.
