CTR is a chaining mode for symmetric block encryption or decryption. Messages are divideded into blocks, and the cipher operation takes place on each block using the secret key and a unique *counter block*. The most straightforward way to fulfil the uniqueness property is to start with an initial, random *counter block* value, and increment it as the next block is processed. The block ciphers from `Crypto.Cipher` (when configured in *MODE_CTR* mode) invoke a callable object (the *counter* para
