Struct KeyRing 

pub struct KeyRing { /* private fields */ }

Holds the master key and derives purpose-specific subkeys via HKDF-SHA256. Key material is zeroized on drop.

Implementations

impl KeyRing

pub fn new(master: Option<&[u8]>) -> Self

Creates a keyring from master, or generates 32 random bytes when None is given.

pub fn subkey(&self, info: &str) -> Result<Zeroizing<[u8; 32]>>

Derives a 32-byte subkey via HKDF-SHA256 with the given info string.

pub fn encrypt( &self, data: &[u8], algorithm: EncryptionAlgorithm, ) -> Result<Vec<u8>>

Encrypts with the default emoji-encryption subkey. Output is nonce(12) || ciphertext.

pub fn decrypt( &self, data: &[u8], algorithm: EncryptionAlgorithm, ) -> Result<Vec<u8>>

Decrypts a nonce(12) || ciphertext payload produced by KeyRing::encrypt. Wrong keys and tampering both surface as MeshError::Crypto.

Trait Implementations

impl Clone for KeyRing

fn clone(&self) -> KeyRing

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for KeyRing

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

Formats the value using the given formatter.
