TCL rc4套餐

我想学习如何使用 TCL rc4 包..我能找到的唯一文档都是具有相同 wiki 的不同站点，并且命令示例不起作用。

示例：

% set keydata [binary format H* 0123456789abcdef]
% rc4::rc4 -hex -key $keydata HelloWorld
3cf1ae8b7f1c670b612f
% rc4::rc4 -hex -key $keydata [binary format H* 3cf1ae8b7f1c670b612f]
HelloWorld

但是，当我运行完全相同的示例时，我得到：

% set keydata [binary format H* 0123456789abcdef]
% rc4::rc4 -hex -key $keydata HelloWorld
3cf1ae8b7f1c670b612f
% rc4::rc4 -hex -key $keydata [binary format H* 3cf1ae8b7f1c670b612f]
48656c6c6f576f726c64

我不确定 rc4 包如何区分加密和解密，实际的命令字符串显示为：

::rc4::rc4 ?-hex? -key keyvalue ?-command lst? ?-out channel? [ -in channel | -infile filename | string ]

另外，-command 是显然不是我正在寻找的，它执行完全不同的功能。我尝试过文件 i/o、echo，但似乎没有任何效果，并且文档中似乎确实缺少一些内容。

有人有使用这个包的经验吗？

原文

I wanted to learn how to use the TCL rc4 package .. the only documentation I can find are all just different sites with the same wiki, and the command example doesn't work.

Example:

% set keydata [binary format H* 0123456789abcdef]
% rc4::rc4 -hex -key $keydata HelloWorld
3cf1ae8b7f1c670b612f
% rc4::rc4 -hex -key $keydata [binary format H* 3cf1ae8b7f1c670b612f]
HelloWorld

However, when I run exactly the same example, I get:

% set keydata [binary format H* 0123456789abcdef]
% rc4::rc4 -hex -key $keydata HelloWorld
3cf1ae8b7f1c670b612f
% rc4::rc4 -hex -key $keydata [binary format H* 3cf1ae8b7f1c670b612f]
48656c6c6f576f726c64

I'm not sure how the rc4 package differentiates between encryption and decryption, the actual command string is shown as:

::rc4::rc4 ?-hex? -key keyvalue ?-command lst? ?-out channel? [ -in channel | -infile filename | string ]

Also, -command is not what I'm looking for apparently, it performs completely different function. I've tries file i/o, echo's, nothing seems to work, and there definitely seems to be something missing from the documentation.

Anyone with experience using this package?
