Struct CipherAES 

pub struct CipherAES {
    pub infos: CryptographicInformation,
    pub sharedsecret: Vec<u8>,
}

Represents the AES cipher for encryption and decryption processes. It holds cryptographic information and a shared secret for operations.

Fields

infos: CryptographicInformation

sharedsecret: Vec<u8>

Implementations

impl CipherAES

Provides AES encryption functionality, handling cryptographic information and shared secrets.

pub fn new(infos: CryptographicInformation) -> Self

Initializes a new CipherAES instance with the provided cryptographic information.

Parameters

• infos: Cryptographic information detailing the encryption or decryption process, content type, and more.

Returns

A new instance of CipherAES.

pub fn get_data(&self) -> Result<Vec<u8>, CryptError>

Retrieves the current data intended for encryption or decryption.

Returns

The data as a vector of bytes (Vec<u8>) or a CryptError if the content cannot be accessed.

pub fn set_shared_secret(&mut self, sharedsecret: Vec<u8>) -> &Self

Sets the shared secret key used for AES encryption and decryption.

Parameters

• sharedsecret: The shared secret as a byte vector.

Returns

A mutable reference to the CipherAES instance, allowing for chaining of operations.

pub fn sharedsecret(&self) -> Result<&Vec<u8>, CryptError>

Retrieves the shared secret key.

Returns

A reference to the shared secret as a byte vector or a CryptError if it cannot be accessed.

pub fn aes_cbc_encrypt(&mut self) -> Result<Vec<u8>, CryptError>

Encrypts the provided data using AES-256 in CBC mode. This function securely generates an IV for each encryption operation.

pub fn aes_cbc_decrypt( &mut self, ciphertext: &[u8], ) -> Result<Vec<u8>, CryptError>

Decrypts data encrypted using AES-256 in CBC mode. Assumes the IV is prepended to the ciphertext.

Trait Implementations

impl Clone for CipherAES

fn clone(&self) -> CipherAES

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl CryptographicFunctions for CipherAES

fn encrypt( &mut self, public_key: Vec<u8>, ) -> Result<(Vec<u8>, Vec<u8>), CryptError>

Performs the encryption process using a public key.

Parameters

• public_key: The public key for encryption.

Returns

A result containing the encrypted data and the ciphertext as a key, or a CryptError.

fn decrypt( &mut self, secret_key: Vec<u8>, ciphertext: Vec<u8>, ) -> Result<Vec<u8>, CryptError>

Performs the decryption process using a secret key and ciphertext.

Parameters

• secret_key: The secret key for decryption.
• ciphertext: The ciphertext to decrypt.

Returns

The decrypted data as a byte vector or a CryptError if decryption fails.

impl Debug for CipherAES

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

Formats the value using the given formatter.

impl Display for CipherAES

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

Formats the value using the given formatter.

impl PartialEq for CipherAES

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