What type of cipher could give ciphertext where for example random ASCII chars between say F-z (symbols and numerals inclusive), but with only a few spaces? Frequency of chars shows some similarities to alphabetic frequency and is 200 chars in length.
I've been reading up on ciphers and have not come across any common ones that would work.
Can someone enlighten me how a seemingly random group of ASCII chars in the given range could be encoded?
Yes, I understand this is broad, so I'm asking what cipher or combination of ciphers could present these observations? I'm happy to research from a jumping off point if someone can point out any thoughts that come to mind
