It's not a key in the typical sense, which is then expanded via another algorithm. OTP key material has to be derived (extracted) from physical processes and events like dice, random key presses or the interaction of laser photons with vacuum energy. You can't use just an algorithm to generate the key. See the OTP tag (crypto.stackexchange.com/questions/tagged/one-time-pad) for more... | |

The question clearly A) considers a random pad moved in person from source to destination, rather than a keystream generated from key and IV by some generator; B) aims at perfect secrecy (resisting an arbitrarily powerful adversary), which a stream cipher does not. | |
