Get a freeware package called "truly random" and generate petabytes of random text. It will look just like one-time pad traffic and ages and eons of computer time will be spent trying to decrypt it. It will be faster too, just one step. Along the way, generate yourself some one-time pads for actual use. It's slow but it is unbreakable if you follow the three rules*. The transmitted traffic will also look just like your random traffic too.

* 1. The key must be the same length as the message.
2. The key must be kept secure.
3. The key must never be re-used.
And, just like the other three rules, there is a fourth corollary:
4. Use message padding and spell out numbers and punctuation.
Chaff (spurious random or pseudo random generated information) generally hasn't been embraced by the crypto community. Too much overhead, too easy to spot as fake. Also it leads to IT folks getting really annoyed and banning blocking said IPs generating high levels of noise. Sometimes NICs go bad and start spewing out random traffic, which is a pain as well.
Btw, this is not directed at you or in anger. Just a generalized thing that I'd like to let folks know. NEVER EVER
EVER USE SOFTWARE RANDOM NUMBER GENERATORS. If it remotely feasible to not use a software RNG, obviously. On the scale of 1 to 10 in terms of bad ideas, it's a "invading during winter while publicly expressing the desire to destroy every vodka distillery in Russia".
Just as another interesting aside, the best source of random numbers is a laser and a single photon counter, that is a silicon PIN detector. The silicon avalanche photodiode (APD) is the cheaper cousin. Photomultiplier tubes (PMT, aka night vision) can work as well. Basically, it can give you a time stamp of when a photon hits the sensor. Toss out the leading bits, and you literally have quantum noise. Probably the absolute platinum standard for randomness. Previous was atmospheric noise. You can get continuous 100Mbps of quantum noise for under $5k. APD would probably be a gold.
And using a webcam's CCD noise as an entropy seed over it would be silver. Maybe 1 Mbps with consumer hardware. Good enough for routine purposes, but not nuclear weapon related security.
