TikZ 节点距离

我对路径和节点的适当间距有疑问。

我想要下面这张图：

我目前正在使用这个代码：

\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{arrows, arrows.meta, positioning, calc}
\begin{document}
\begin{tikzpicture}[node distance=1cm, auto]  
\tikzset{
    block/.style= {draw, rectangle, align=center,minimum width=2cm,minimum height=1cm},
    >={Classical TikZ Rightarrow[length=1.7mm]},
    XOR/.style={draw,circle,append after command={
        [shorten >=\pgflinewidth, shorten <=\pgflinewidth,]
        (\tikzlastnode.north) edge (\tikzlastnode.south)
        (\tikzlastnode.east) edge (\tikzlastnode.west)}}
}
%}  
\node[] (k) {k};
\node[right=of k] (t) {t};
\node[block, below =2cm of t] (AES) {AES};
\node[above =1cm of AES] (splitof) {};
\node[XOR, below =1cm of AES] (xor) {};
\node[below =1.5cm of xor] (c) {c};

%% paths
\path[draw,->] (k) |- (AES);
\path[draw,->] (AES) edge (xor);
\path[draw,->] (t) edge (AES);
\path[draw,->,style={shorten <=-1.1mm}] (splitof) -- +(2, 0) |- (xor);
\path[draw,->] (xor) edge (c);

\end{tikzpicture} 
\end{document}

我不明白为什么我需要style={shorten <=-1.1mm}在隐藏节点上使用这个指令。所有其他箭头在它们的节点上都完全对齐，但这个箭头只是在节点上稍微留出一点空间。

免责声明：这是我第一次尝试使用 Ti钾Z 和上面的代码是 c&p 工作。

您应该使用坐标而不是“隐藏节点”，因为它似乎\node[above =1cm of AES, text width=0mm, inner sep=0mm, outer sep=0mm] (splitof) {};需要一些空间。

以下是无需缩短即可运行的代码：

% arara: pdflatex

\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{arrows.meta, positioning}

\begin{document}
\begin{tikzpicture}
    \tikzset{%
        ,block/.style={%
            ,draw
            ,rectangle
            ,align=center
            ,minimum width=2cm
            ,minimum height=1cm
            }
        ,>={Classical TikZ Rightarrow[length=1.7mm]}
        ,XOR/.style={%
            ,draw
            ,circle,append after command={%
                [shorten >=\pgflinewidth, shorten <=\pgflinewidth,]
                (\tikzlastnode.north) edge (\tikzlastnode.south)
                (\tikzlastnode.east) edge (\tikzlastnode.west)
                }
            }
        }
    \node (k) {k};
    \node[right=of k] (t) {t};
    \node[block, below =2cm of t] (AES) {AES};%
    \coordinate[above =1cm of AES] (splitof) {};
    \node[XOR, below =1cm of AES] (xor) {};
    \node[below =1.5cm of xor] (c) {c};

    \path[draw,->] (k) |- (AES);
    \path[draw,->] (AES) edge (xor);
    \path[draw,->] (t) edge (AES);
    \path[draw,->] (splitof) -- +(2, 0) |- (xor);
    \path[draw,->] (xor) edge (c);  
\end{tikzpicture} 
\end{document}
