Key derivation purpose — maps to HKDF info strings for flat (non-parameterized) keys.

Variants

Signing

THE identity signing key (Ed25519). Used for: mesh signing, git commits, personal attribution. Identity hash = SHA-256(pubkey) truncated to 16 bytes. This IS you.

RnsEncryption

RNS X25519 encryption key.

Age

age X25519 encryption key.

WireGuard

WireGuard Curve25519 key.

SshHost

SSH host Ed25519 key (identifies the machine, not the person).

Yggdrasil

Yggdrasil Ed25519 key (IPv6 overlay network identity).

I2pSigning

I2P destination Ed25519 signing key.

I2pEncryption

I2P destination X25519 encryption key.

Tor

Tor onion v3 service Ed25519 key.

RnsSigning

👎Deprecated:

use KeyPurpose::Signing — RnsSigning and GitSigning are now unified

Legacy alias for Signing. Derives identical bytes.

GitSigning

👎Deprecated:

use KeyPurpose::Signing — RnsSigning and GitSigning are now unified

Legacy alias for Signing. Derives identical bytes.

Implementations

impl KeyPurpose

pub fn info(&self) -> &'static [u8]

HKDF info string for this purpose.

pub fn all() -> &'static [KeyPurpose]

All current (non-deprecated) purposes.

Trait Implementations

impl Clone for KeyPurpose

fn clone(&self) -> KeyPurpose

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for KeyPurpose

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for KeyPurpose

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for KeyPurpose

fn eq(&self, other: &KeyPurpose) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
