Problem 61046. Decipher Message Using Prime of Primitive Root of Two Sequence Key

Provided a message with all characters <= 255 (ascii) as an input, decode the padded message (removing the random character pad), XORing input converted to binary vector (8 bits each) with the inputted prime having primitive root of two as the key. The key is the repeated sequence of 2^x modulo prime key input starting from x=0 until the cycle repeats (unpadded zero binary represented vector of the repeated sequence). After XORing, remove the padded front and return the character array as output.
