Struct EncryptedMessage

pub struct EncryptedMessage {
    pub nonce: [u8; 12],
    pub tag: [u8; 16],
    pub len: usize,
}

All encrypted messages must have associated state data (nonce, tag)

Fields

nonce: [u8; 12]

Provides storage for chacha20poly1305::Nonce

tag: [u8; 16]

Provides storage for chacha20poly1305::Tag

len: usize

Length of follow-on data. Data is not owned directly to prevent copies

Implementations

impl EncryptedMessage

pub fn encrypt( key: &[u8], nseq: &mut NonceSequence, data: &mut [u8], ) -> Result<Self, Box<dyn Error>>

Create an encrypted message out of an arbitrary serializable type

pub fn decrypt( &mut self, key: &[u8], data: &mut [u8], ) -> Result<usize, Box<dyn Error>>

Decrypt the provided data in-place

Trait Implementations

impl Clone for EncryptedMessage

fn clone(&self) -> EncryptedMessage

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EncryptedMessage

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

Formats the value using the given formatter.

impl Default for EncryptedMessage

fn default() -> EncryptedMessage

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for EncryptedMessage

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for EncryptedMessage

fn eq(&self, other: &EncryptedMessage) -> 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 EncryptedMessage

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
