Struct double_ratchet_rs::RatchetEncHeader

pub struct RatchetEncHeader { /* private fields */ }

A Ratchet, but with header encryption.

Implementations

impl RatchetEncHeader

pub fn init_alice( sk: [u8; 32], bob_dh_public_key: PublicKey, shared_hka: [u8; 32], shared_nhkb: [u8; 32] ) -> Self

Initialize a RatchetEncHeader with a remote PublicKey. Initialized second. Requires a shared key, a PublicKey, a shared HKA, and a shared NHKB. Returns a RatchetEncHeader.

pub fn init_bob( sk: [u8; 32], shared_hka: [u8; 32], shared_nhkb: [u8; 32] ) -> (Self, PublicKey)

Initialize a RatchetEncHeader without a remote PublicKey. Initialized first. Requires a shared key, a shared HKA, and a shared NHKB. Returns a RatchetEncHeader and a PublicKey.

pub fn encrypt( &mut self, data: &[u8], associated_data: &[u8] ) -> (EncryptedHeader, Vec<u8>, [u8; 12])

Encrypt bytes with a RatchetEncHeader. Requires bytes and associated bytes. Returns an EncryptedHeader, encrypted bytes, and a nonce.

pub fn decrypt( &mut self, enc_header: &EncryptedHeader, enc_data: &[u8], nonce: &[u8; 12], associated_data: &[u8] ) -> Vec<u8>

Decrypt encrypted bytes with a RatchetEncHeader. Requires an EncryptedHeader, encrypted bytes, a nonce, and associated bytes. Returns decrypted bytes.

pub fn decrypt_with_header( &mut self, enc_header: &EncryptedHeader, enc_data: &[u8], nonce: &[u8; 12], associated_data: &[u8] ) -> (Vec<u8>, Header)

Decrypt encrypted bytes and an EncryptedHeader with a RatchetEncHeader. Requires an EncryptedHeader, encrypted bytes, a nonce, and associated bytes. Returns decrypted bytes and a Header.

pub fn export(&self) -> Vec<u8>

Export a RatchetEncHeader. Returns bytes.

pub fn import(data: &[u8]) -> Option<Self>

Import a previously exported RatchetEncHeader. Requires bytes. Returns a RatchetEncHeader, or nothing if invalid data is provided.

Trait Implementations

impl Debug for RatchetEncHeader

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for RatchetEncHeader

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Drop for RatchetEncHeader

fn drop(&mut self)

Executes the destructor for this type.

impl PartialEq<RatchetEncHeader> for RatchetEncHeader

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl Serialize for RatchetEncHeader

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

Serialize this value into the given Serde serializer.

impl Zeroize for RatchetEncHeader

fn zeroize(&mut self)

Zero out this object from memory using Rust intrinsics which ensure the zeroization operation is not “optimized away” by the compiler.
