virtual size_t ivSize() const =0
Size of the initialization vector for this cipher, in bytes.
Abstract base class for stream ciphers.
Definition: Cipher.h:29
virtual void encrypt(uint8_t *output, const uint8_t *input, size_t len)=0
Encrypts an input buffer and writes the ciphertext to an output buffer.
virtual void decrypt(uint8_t *output, const uint8_t *input, size_t len)=0
Decrypts an input buffer and writes the plaintext to an output buffer.
virtual bool setIV(const uint8_t *iv, size_t len)=0
Sets the initialization vector to use for future encryption and decryption operations.
Cipher()
Constructs a new cipher object.
Definition: Cipher.cpp:41
virtual ~Cipher()
Destroys this cipher object.
Definition: Cipher.cpp:53
virtual size_t keySize() const =0
Default size of the key for this cipher, in bytes.
virtual void clear()=0
Clears all security-sensitive state from this cipher.
virtual bool setKey(const uint8_t *key, size_t len)=0
Sets the key to use for future encryption and decryption operations.
