I've been trying to decode the following sentence for a few days:
Humankind's greatest invention “tlvtl://xnw.rn/5RcQs4U”
I tried using the Vigenere cipher, Beaufort Cipher with no success. The key's that I tried were also taken from googling "humankind's greatest invention". The only thing that worked was the Jefferson Wheel cipher, however that let me to the wrong URL (https://ibb.co/qxdF9w8). I have strong concerns that the encrypted link is as well an ibb.co one.
Any ideas would be welcome!
