How do I decrypt the following encryption code ?

encrypt5: push eax
        mov  al, byte ptr[eax]
        push ecx
        and eax, 0x7C
        ror eax, 1
        ror eax, 1
        inc eax
        mov edx, eax
        pop ecx
        pop eax
        mov byte ptr[eax], dl
        xor edx, ecx
        mov eax, edx
        rol al, 1
        ret
