Explanation:

The shift for the current letter is always the index of the previous letter in the standard latin alphabet. If there is no previous letter, the shift is 12. (Still trying to figure out why) So in other words, it's a vigenere cipher with the key
"o" + encryptedText

• @JonathanAllan Oh wow... It amazes me how I missed that. I have to figure that out quickly :(( panics

• @JonathanAllan Because an "o" was used instead of an "a"
