Struct yaca::DecryptContext

pub struct DecryptContext { /* fields omitted */ }

Context for Decrypt operations

Implementations

impl DecryptContext

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

Initializes a decryption context

• Parameters passed must match the parameters used to encrypt the data.
• See EncryptContext::initialize()

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

Decrypts chunk of the data

• ciphertext is a chunk of encrypted data to be decrypted.
• Returns a chunk of decrypted data.

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

Decrypts the final chunk of the data

• Returns the final chunk of decrypted data.
