    push 0x7171444e     ; store our code in little endian
    push rsp            ; return pointer
    pop rax
    push rax
    sub al, 48          ; needed to make xor printable code
    push rax            ; copy rax into rcx
    pop rcx
    push 0x41414141     ; syscall code block key
    pop rax
    xor [rcx+48], eax   ; decode the sycall code block using an offset for more ass pulling
    push 0x4e           ; encoded syscall number for exit
    pop rax
    xor al, 0x72        ; xor it with the key
