comment How to break an arbitrary XOR and Rotation based encryption?
Can you further expand your question, what are you XORing, what are you rotating, when and in what order are you performing these operations?

comment Difference between encrypting something and hashing something
Actually, it is not a random permutation, it is a VERY DETERMINISTIC permutation (normally) based on a random input (i.e. the key). By definition, if it were truly a "random" permutation, it would not be reversible.
