the cipher works by taking a single letter. for instance, "A" and then splitting it into 2 letters. say "B" and "C" then you take the "B" and split it by 2 into say "JK" and then split "C" into say "LD" the resulting four letters are "JKLD" which collectively represent "A". so, for example, the word "hi" could be encrypted as "HJKLOPJH" it is always read left to right. and the letters that the word is being split into are always random. in this case each letter of the word being split into 2 letters which are then themselves split into 2 letters effectively multiplying the size of any plaintext run through this cipher by 4. so, remember that for every 4 characters, 1 letter is represented. so simply divide the number of characters by 4 and you have the number of letters being encrypted. which should prove helpful? I guess. whatever. that should be enough information for people to solve this next sentence.

solve the following: each word is separated by a " : " to make things easier.

please tell me about the problems with this cipher (although to make it easier to decipher I did make it simpler by removing the possibility of special characters and numbers as well as restricting the order of the letters to only one combination and also restricting the number of characters per letter and other stuff like how many characters you can split a single letter into so this one is a much simpler so have fun
