My understanding is that the three most popular approaches to "steganography using text as a cover" are:
1 Generate a completely new text by picking one word at a time from a dictionary, using the ciphertext bits to select which word.
Pick words in ways that, at first glance, look like real English sentences, using Markov chain algorithms.

The most famous text based steganographic scheme is using the first letters of words / sentences. If the mean sentence length is 15-20 words and mean word length is 5 letters, then efficiency is ~1%. You could use shorter than average sentences and/or words to increase the efficiency to within your bounds of >2%.
Obviously this is a specific example of a ...

In his answer Michael mentioned a known stego scheme of using the first characters of words/sentences as stego characters and rightly remarked that the scheme can be practically applied ("user-friendly") only when the stego character sequence is in natural language (i.e. not encrypted, in which case the scheme is however evidently very weak) and
not when the ...

Your question is really too general - and perhaps off-topic, as steganography is quite a different field to cryptography.
That being said, the answer to your question really depends on many things. Steganography is the art of hiding information in plain-sight. This information could be hidden in either; analogue or digital media, on the internet or in a ...

Brute forcing the password, since no useful cryptanalysis of ICE is known.
I'm really more of a theory guy, so I don't know of any tools for this, but there are some resources that I've found.

You could use a Cardano grille to solve the problem of steganography (not encryption.) Very difficult to identify or even detect, as long as care is taken when hand-lettering the final message. If the mask's letters are too dense, the language of the cover message needed to conform to those letters can get a bit tortuous.
Also note the grille doesn't need ...
