Expand description

Types which can be initialized from a key and initialization vector (nonce).

Required Methods§

Source

fn new(key: &Array<u8, Self::KeySize>, iv: &Array<u8, Self::IvSize>) -> Self

Create new value from fixed length key and nonce.

Provided Methods§

Source

fn new_from_slices(key: &[u8], iv: &[u8]) -> Result<Self, InvalidLength>

Create new value from variable length key and nonce.

§Errors

Returns InvalidLength in the event that key and/or iv are not the expected length.

Source

fn generate_key<R>(rng: &mut R) -> Array<u8, Self::KeySize>
where R: CryptoRng,

👎Deprecated since 0.2.0: use the Generate trait impl on Key instead

DEPRECATED: generate random key using the provided CryptoRng.

Instead, you can now use the Generate trait directly with the Key type:

ⓘ
let key = Key::generate_from_rng(rng);
Source

fn generate_iv<R>(rng: &mut R) -> Array<u8, Self::IvSize>
where R: CryptoRng,

👎Deprecated since 0.2.0: use the Generate trait impl on Iv instead

DEPRECATED: generate random IV using the provided CryptoRng.

Instead, you can now use the Generate trait directly with the Iv type:

ⓘ
let iv = Iv::generate_from_rng(rng);
Source

fn generate_key_iv<R>( rng: &mut R, ) -> (Array<u8, Self::KeySize>, Array<u8, Self::IvSize>)
where R: CryptoRng,

👎Deprecated since 0.2.0: use the Generate trait impls on Key and Iv instead

DEPRECATED: generate random key and IV using the provided CryptoRng.

Instead, you can now use the Generate trait directly with the Key and Iv types:

ⓘ
let key = Key::generate_from_rng(rng);
let iv = Iv::generate_from_rng(rng);

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.

Implementations on Foreign Types§
