Struct EphemeralEcdhContent 

pub struct EphemeralEcdhContent {
    pub ciphertext: Vec<u8>,
    pub nonce: [u8; 12],
    pub ephemeral_public: [u8; 32],
}

Ephemeral ECDH ChaCha20-Poly1305 encrypted content Simple public key encryption using ephemeral X25519 keys Anyone can encrypt for the recipient using only their public key

Fields

ciphertext: Vec<u8>

Encrypted data + authentication tag

nonce: [u8; 12]

ChaCha20-Poly1305 nonce (12 bytes)

ephemeral_public: [u8; 32]

Ephemeral X25519 public key (generated randomly for each message)

Implementations

impl EphemeralEcdhContent

pub fn encrypt( plaintext: &[u8], recipient_ed25519_public: &VerifyingKey, ) -> Result<Self, CryptoError>

Encrypt data using ephemeral X25519 ECDH
Generates a random ephemeral key pair for each message Anyone can encrypt for the recipient using only their Ed25519 public key

pub fn decrypt( &self, recipient_ed25519_key: &SigningKey, ) -> Result<Vec<u8>, CryptoError>

Decrypt data using ephemeral X25519 ECDH Recipient uses their Ed25519 private key + stored ephemeral public key

Trait Implementations

impl Clone for EphemeralEcdhContent

fn clone(&self) -> EphemeralEcdhContent

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EphemeralEcdhContent

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for EphemeralEcdhContent

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for EphemeralEcdhContent

fn eq(&self, other: &EphemeralEcdhContent) -> 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.

impl Serialize for EphemeralEcdhContent

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
