Is it possible that coptmuer experts who work for the authorities will be able to crack the code and read the ReadMe file?Not likely unless the person doing the encryption used a passphrase like password or passphrase or abcdef . They've used strong encryption which, with a reasonably long and non-obvious passphrase, isn't crackable in practice (brute force methods even using the most powerful supercoptmuers on the planet would take lifetimes, at least).I wouldn’t expect the Norfolk police to have those capabilities, but surely the British government has people who know how to decipher encrypted files and trip-up hackers. I read how the British got the Enigma machine and read the German code during WWII.Actually, Polish mathematicians who had access to a commercial version of the 3-rotor Enigma machine figured out how to crack it. They were helped by the fact that, while training, the German Army used sequential keys to specify the rotor settings ( AAA today, AAB tomorrow, etc) which allowed them to figure out the physical rotor wiring eventually making use of redundancy in the data, and statistically analyzing patterns in the possible mappings for specific rotor combinations, etc.They brought it to the Brits along with the first Bombe cracking machine, which was built out of Enigma copies made by the Poles. The Brits were able to design an all-electronic Bombe which was orders of magnitudes faster, and stole most of the credit besides The German Navy used a 4-rotor version of Enigma which the British weren't able to crack. If you're familiar with the story of the British boarding a sinking German U-Boat and grabbing the one-use pads of keys and the set of actual rotors used at the time, the importance of this was *precisely* the fact that the 4-rotor version plus (in general) much tighter operating standards meant the Brits had been unable to read the U-Boat communiques. While at the same time they read the German army's mail.Current strong encryption algorithms are literally billions of times harder to crack, though modern systems are cracked when someone figures out how to step around the encryption (by stealing passphrases, etc).

If the image must work well with black & white neither of these two will work very well. Not unlses you tweak the contrast a bit.Problem being with the first it falls within light/medium values and not enough dark values; the opposite is the problem with the second plenty of medium/dark values but no light values.
