使用 Powershell 加密解密我正在尝试使用 runprogram/powershell 加密有效 JSL 的列表。由于性能原因，这只是对 powershell 的一次调用，这一点很重要。我以为我可以正常工作，但意识到单引号或双引号在嵌套列表中会让我感到困惑。
此外，我无法写入文件并让 powershell 读取该文件。效果很好，但不允许这样做。我想我只是因为 JSL 和 C 以及 Powershell 的转义而崩溃了。

encryption_key = J(16, 1, randominteger(0, 255));
unencrypted_input = {"Fa'ke\!"", {Empty(), "Str'\!"ing"}}; // this one breaks me
unencrypted_input = {"Fake", {Empty(), "String"}}; // this one is fine
print("encryptng");
init_str = "@("; // creating a powershell array
for(i=1, i<=nitems(unencrypted_input), i++,
if(i!=1, init_str ||= ", ");
item = unencrypted_input[i];
// for encrypt we want to put it in quotes so we can pull it out later so we can parse;
if( isstring(item), item = "\!""||char(item)||"\!"");
// because of the way runprogram works we have to C escape the quotes as well
init_str ||= "\\!""||substitute(char(item), "\!"", "'")||"\\!"";

脚本编写回复：使用 Powershell 加密解密我认为关键是去/从一个 powershell 阵列。
也许这让事情更容易理解

Re: 使用 Powershell 加密解密我试图用 [quote] 来做到这一点，但由于 char（包含字符串的列表）的工作方式，我无法让它工作。我不能让powershell给我引号，它只是去掉引号，所以当我把它拉回来（如果它里面也有引号）然后它搞砸了解析。我也许可以制作一个具有深度的递归函数，以便它进入并将所有东西变成我需要的东西，然后只包装顶层。如果那有意义的话。

ll = {"Fak'e\!"", {Empty(), "Str'\!"ing"}};
char(ll); // "{\!"Fak'e\!\!\!"\!", {Empty(), \!"Str'\!\!\!"ing\!"}}"
