Struct SymmetricEncryptedMessage 

pub struct SymmetricEncryptedMessage {
    pub ciphertext: Vec<u8>,
    pub nonce: [u8; 12],
    pub associated_data: Option<Vec<u8>>,
}

A complete encrypted message containing ciphertext and nonce

This structure packages the encrypted data with its nonce for easy serialization and transmission.

Fields

ciphertext: Vec<u8>

The encrypted data

nonce: [u8; 12]

The nonce used for encryption

associated_data: Option<Vec<u8>>

Optional associated data that was authenticated

Implementations

impl EncryptedMessage

pub const fn new( ciphertext: Vec<u8>, nonce: [u8; 12], associated_data: Option<Vec<u8>>, ) -> EncryptedMessage

Create a new encrypted message

Arguments

• ciphertext - The encrypted data
• nonce - The nonce used for encryption
• associated_data - Optional associated data

pub fn decrypt( &self, cipher: &ChaCha20Poly1305Cipher, ) -> Result<Vec<u8>, SymmetricError>

Decrypt this message using the provided cipher

Arguments

• cipher - The cipher to use for decryption

Returns

The decrypted plaintext

Errors

Returns SymmetricError::DecryptionFailed if decryption fails

pub fn size(&self) -> usize

Get the size of the encrypted message in bytes
