Enum BlockCipherMode 

#[non_exhaustive]
pub enum BlockCipherMode {
    CFB,
    CBC,
    ECB,
}

Block cipher mode of operation.

Block modes govern how a block cipher processes data spanning multiple blocks.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

CFB

Full-block cipher feedback mode.

CBC

Cipher block chaining.

ECB

Electronic codebook mode.

Note: do not use as-is. Patterns in the plaintext will be visible as patterns in the ciphertext. Mind the penguin!

Implementations

impl BlockCipherMode

pub fn requires_padding(&self) -> bool

Returns whether the mode requires padding.

Some modes only operate on complete blocks, so if the plaintext’s length is not a multiple of the symmetric algorithm’s block size, padding is required.

Trait Implementations

impl Clone for BlockCipherMode

fn clone(&self) -> BlockCipherMode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BlockCipherMode

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

Formats the value using the given formatter.

impl Hash for BlockCipherMode

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for BlockCipherMode

fn eq(&self, other: &BlockCipherMode) -> 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.
