Struct tindercrypt::metadata::EncryptionMetadata

pub struct EncryptionMetadata {
    pub nonce: [u8; 12],
}

The metadata that can be used for the encryption process.

Examples

use tindercrypt::metadata::EncryptionMetadata;

// Generate a struct instance for the encryption metadata.
let enc_meta1 = EncryptionMetadata::generate();

// Generate a second struct instance. The nonce should be different this time.
let enc_meta2 = EncryptionMetadata::generate();
assert_ne!(enc_meta1.nonce, enc_meta2.nonce);

Fields

nonce: [u8; 12]

The nonce value for the AEAD algorithms.

Nonces are unique, 96-bit values, which are filled with random data.

Implementations

impl EncryptionMetadata

pub fn new(nonce: [u8; 12]) -> Self

Create the encryption metadata from user-provided values.

This method should be used only when the user wants to explicitly set a specific value. Else, it’s better to use ::generate().

pub fn generate() -> Self

Generate encryption metadata.

Trait Implementations

impl Clone for EncryptionMetadata

fn clone(&self) -> EncryptionMetadata

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for EncryptionMetadata

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

Formats the value using the given formatter.

impl PartialEq<EncryptionMetadata> for EncryptionMetadata

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

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

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

This method tests for !=.
