Class Nettle.BufferedCipher()->Buffer.State

Description

Acts as a buffer so that data can be fed to the cipher in blocks that don't correspond to cipher block sizes.

Example

class Encrypter
   {
     protected Crypto.Cipher buffer;
     void create(string key)
     {
       buffer = Crypto.AES.CBC.Buffer();
       buffer->set_encrypt_key(key);
     }
     string feed(string data)
     {
       return buffer->crypt(data);
     }
     string drain()
     {
       return buffer->pad(Crypto.PAD_PKCS7);
     }
   }

Method create

Nettle.BufferedCipher.Buffer.State Nettle.BufferedCipher.Buffer.State()

Description

Initialize the buffer with the Cipher::State object returned by substate_factory(). This is usually the State for the cipher implemented in the parent module.
