Struct EncryptedFile 

pub struct EncryptedFile {
    header: FileHeader,
    ciphertext: Vec<u8>,
}

Represents a complete encrypted file with header and content

Fields

header: FileHeader

ciphertext: Vec<u8>

Implementations

impl EncryptedFile

pub fn new(header: FileHeader, ciphertext: Vec<u8>) -> EncryptedFile

pub fn seal( plaintext_file: &PlaintextFile, key: &SecureKey, kdf_params: KeyDerivationParams, salt: [u8; 16], content_nonce: [u8; 24], filename_nonce: [u8; 24], ) -> Result<EncryptedFile, FileError>

Encrypts a plaintext file into a complete v2 encrypted file.

This owns the v2 AEAD choreography: the fixed header fields are bound as associated data to both ciphertexts, with distinct domains for filename and content, so neither the header nor the pairing of the two ciphertexts can be tampered with undetected.

The caller supplies the key (derived from kdf_params and salt) and fresh random salt/nonces, keeping this function deterministic.

pub fn from_bytes(bytes: &[u8]) -> Result<EncryptedFile, HeaderError>

Parses a serialized v2 file into its header and content ciphertext.

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

Serializes the complete file (header followed by content ciphertext).

pub fn decrypt(&self, key: &SecureKey) -> Result<PlaintextFile, FileError>

Decrypts the filename and content, verifying the header binding under each ciphertext’s own domain. The inverse of EncryptedFile::seal.

pub fn header(&self) -> &FileHeader

pub fn ciphertext(&self) -> &[u8]
