Aes256Ctr

AES with a 256-bit key in CTR mode

Aes128Gcm

Implementations

impl Cipher

pub fn block_size(&self) -> usize

Returns the block size of the cipher.

pub fn key_len(&self) -> usize

Returns the key size of the cipher.

pub fn iv_len(&self) -> usize

Returns the IV size of the cipher.

pub fn tag_size(&self) -> u32

Returns the tag size of the cipher.

An AE-cipher results into a

1. ciphertext
2. tag

Ciphertext and tag are both stored in a block of the container. Use this method to get the size of the tag. For a non-AE-cipher the tag-size is 0.

Trait Implementations

impl Clone for Cipher

fn clone(&self) -> Cipher

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Cipher

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

Formats the value using the given formatter.

impl Display for Cipher

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

Formats the value using the given formatter.

impl FromStr for Cipher

type Err = ()

The associated error which can be returned from parsing.

fn from_str(str: &str) -> Result<Self, ()>

Parses a string s to return a value of this type.

impl PartialEq for Cipher

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Copy for Cipher

impl StructuralPartialEq for Cipher
