Swusjask_Encryption

One day swusjask woke up and decided to be cryptography researcher. Suddenly, he came up with mind that he want to create some encryption scheme like RSA. RSA is widely known and used as cryptography encryption scheme and work in equation under multiplication. So he came up with mind that "Why I not make encryption scheme more complicated to improve security". So he decided to make encryption scheme under equation with own defined multiplication operation. But, the problem is he forgot to make decryption scheme 😔.
