If we need to cipher 26 letters, the simple way is to transfer the letters to numbers. For example, 1 represent A, 2 represent B and so on. If we want to cipher "number" use binary conversion, it will change to "1110 10101 1101 10 101 10010 1111 1110 101". If we use decimal conversion, the cipher message is "14 21 13 2 5 18 15 14 5"
Besides, we can use reverse to increase difficulty to decipher. For example, the plaintext is "This is a test." If we reverse the whole sentence, the cipher message will be :"tset a si siht." If we reverse every word, the cipher message turns to:"siht si a tset." To improve the cipher, we could also add the number cipher method no matter it is binary conversion or decimal conversion. You can have a try!~
Wow I really like how you introduce possibly using multiple different methods with one message. The reversing is a good idea since it would further encode the text and use of the numbers on top of that would be very confusing for someone to analyze. You could also possibly think of just reversing some words within the reversed sentence to make the pattern less detectable or change the number code too. Just some other things to think about.
