Enum ContentEncryption 

pub enum ContentEncryption {
    A256GCM,
    A128GCM,
}

Content encryption algorithm identifier.

Variants

A256GCM

AES-256-GCM (recommended default)

A128GCM

AES-128-GCM

Implementations

impl ContentEncryption

pub fn alg_name(&self) -> &'static str

Get the JWE “enc” header value for this algorithm.

pub fn from_alg_name(name: &str) -> Result<Self, Error>

Parse a content encryption algorithm from its JWE name.

pub fn key_size(&self) -> usize

Get the required key size in bytes.

pub fn iv_size(&self) -> usize

Get the IV size in bytes.

pub fn tag_size(&self) -> usize

Get the authentication tag size in bytes.

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

Generate a random Content Encryption Key (CEK) for this algorithm.

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

Generate a random IV for this algorithm.

pub fn encrypt( &self, cek: &[u8], iv: &[u8], aad: &[u8], plaintext: &[u8], ) -> Result<(Vec<u8>, Vec<u8>), Error>

Encrypt plaintext using the content encryption algorithm.

Returns (ciphertext, authentication_tag).

pub fn decrypt( &self, cek: &[u8], iv: &[u8], aad: &[u8], ciphertext: &[u8], tag: &[u8], ) -> Result<Vec<u8>, Error>

Decrypt ciphertext using the content encryption algorithm.

Returns the plaintext.

Trait Implementations

impl Clone for ContentEncryption

fn clone(&self) -> ContentEncryption

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ContentEncryption

impl Debug for ContentEncryption

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

Formats the value using the given formatter.

impl Default for ContentEncryption

fn default() -> ContentEncryption

Returns the “default value” for a type.

impl Eq for ContentEncryption

impl PartialEq for ContentEncryption

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