A C-shaped forearm brace attaches to a bow through a support and a bracket that is attached to the front of a bow’s riser. The adjusting block is slidably received in the lock cylinder and has a wedge side facing the lock cylinder and a plurality of first wedge elements formed on the wedge side. As the pressurized hydrocarbons flow through a succession of plates at each equidistant helical level, the elongate helix rotates synchronously with the upwardly flowing hydrocarbons within the production tubing string. A decryption engine decrypts the ciphertext using a key-based decryption algorithm corresponding to the key-based encryption algorithm.
