Australia's promised “not-a-backdoor” crypto-busting bill is out and the government has kept its word - it doesn't want a backdoor, just the keys to your front one.
The draft of The Assistance and Access Bill 2018 calls for anyone using or selling communications services in Australia will be subject to police orders for access to private data.
That includes all vendors of computers, phones, apps, social media and cloud services in the Lucky Country, and anyone within national borders using them. These data-tapping orders will be enforced with fines of up to AU$10m (US$7.3m) for companies or $50,000 ($36,368) for individuals
The draft legislation also wants five years in prison for anyone who reveals a data-slurping investigation is going on. And while there's no explicit encryption backdoor requirements in the 110 page draft bill, our first look suggests there doesn't need to be.

Some story I recently consumed about WWII African mail back home included a bit about the code that the corresponding couple used to communicate through the censors. They basically blathered on about inane stuff like the recent cricket match, the weather, somebody's scorpion bite, whatever, and the real message was encoded in the second letter of each first word on each line. The messages were still somewhat cryptic, such as "bowlerhatsoon", but that's enough for one to tell the other that they are being discharged (only civilians wear bowler hats) and rotating home soon, which is big/important news that the censors would have struck out (simply discarded the letter, most likely). The censors were free to read the entire message, but unable to decipher the true meaning and of course let it pass.
No information theory will ever manage to prove or disprove the existence of such messages, as long as you're allowed to send enough crap along, and with people sharing 16MP color photos of their meals every day, plus cat videos, I think there's plenty of bandwidth in which to cleverly hide just about any text you might ever want to communicate.

That's reminiscent of the Japanese code book encryption, and to the Navajo communications, both in WWII as well.
It's worth noting that the reason why code books are secure, is that nobody understands the meaning of the individual words. However, the more they are used, and the more you can perform analysis of subsequent events associated with the coded conversations, the more you can deduce their meaning.
Code books not invulnerable precisely because they reuse the codes, and the opposite is the reason why one-time-pad encryption is the only provably unbreakable encryption around. One of the reasons why the Navajo were so secure is noted in bold above. That would not have protected them though over time, if the Japanese or Germans had enough transmissions and activity to analyze.
What you refer to at the end is Steganography, which can be combined with deniable encryption to encode messages in the random noise found in pretty much all pictures. Especially pictures in a night time setting produced by equipment not suited to low-light conditions.
WWII is indeed a very fascinating time period for the study of encryption.
Technically, lunchtime is at any moment. It's just a wave function.
