Okay, this is a simple text encoder that uses a cryptogram I made up. If a letter is a consonant (bcd,fgh,jklmn,pqrst,vwxyz), then it replaces it with the next consonant. If the letter is a vowel (a,e,i,o,u), then it replaces it with the next vowel. Because it is very hard to pronounce words without vowels, changing the vowel rather than making it a consonant makes the output *almost* readable; it sounds like some foreign language.
Try it out, enter some text and click “Encode it”. Or you can enter some already-encoded text and click “Decode it” to see what it says. To get a different cypher, use “Decode it” on the message; to get the origional message from that, use “Encode it” - they undo each other, no matter which order they are run in.
