Struct yaca::EncryptContext

pub struct EncryptContext { /* fields omitted */ }

Context for Encrypt operations

Implementations

impl EncryptContext

pub fn get_iv_length(
    algo: &EncryptAlgorithm,
    bcm: &BlockCipherMode,
    key_length: &KeyLength
) -> Result<Option<KeyLength>>

Returns the recommended/default length of the Initialization Vector for a given encryption configuration

• If None returned that means that for this specific algorithm and its parameters Initialization Vector is not used.

pub fn initialize(
    algo: &EncryptAlgorithm,
    bcm: &BlockCipherMode,
    sym_key: &Key,
    iv: Option<&Key>
) -> Result<EncryptContext>

Initializes an encryption context

• algo is an encryption algorithm used to encrypt the data.
• bcm is a chaining mode used to encrypt the data.
• sym_key is a symmetric key used to encrypt the data.
• iv is an optional Initialization Vector used to encrypt the data, see EncryptContext::get_iv_length()

pub fn update(&self, plaintext: &[u8]) -> Result<Vec<u8>>

Encrypts chunk of the data

• plaintext is a chunk of data to be encrypted.
• Returns a chunk of encrypted data.

pub fn finalize(&self) -> Result<Vec<u8>>

Encrypts the final chunk of the data

• Returns the final chunk of encrypted data.
