Enum pzip::Algorithm

pub enum Algorithm {
    AesGcm256,
}

The encryption algorithms known by PZip.

Encapsulates the enryption, decryption, key wrapping, and tags required for each algorithm.

Variants

Implementations

impl Algorithm

pub fn from(num: u8) -> Result<Algorithm, Error>

Returns an Algorithm for the specified u8 if known, otherwise Error::UnknownAlgorithm.

pub fn tags(&self) -> PZipTags

Returns the PZipTags to be used for new PZip files using this algorithm.

Generally, this should return suitable random defaults for any encryption parameters. Specifically, for AES-GCM, this returns a Tag::Nonce with 12 random bytes.

pub fn wrap_key(&self, key_bytes: &[u8]) -> Result<LessSafeKey, Error>

Wraps the (either raw or already-derived) key bytes into a LessSafeKey than can be used for encryption and decryption with this algorithm.

pub fn encrypt(
    &self,
    key: &LessSafeKey,
    data: &[u8],
    tags: &PZipTags,
    counter: u32
) -> Result<Vec<u8>, Error>

Encrypts a block of data.

pub fn decrypt(
    &self,
    key: &LessSafeKey,
    data: &[u8],
    tags: &PZipTags,
    counter: u32
) -> Result<Vec<u8>, Error>

Decrypts a block of data.

Trait Implementations

impl Clone for Algorithm
