将vbs加密脚本转换为字符串

标签: vbscript

我有一个.vbe(.vbs)文件,其中包含由screnc生成的加密脚本。 将加密脚本转换为字符串然后将其从字符串转换回加密的正确方法是什么?

我想我应该指出我的问题。我创建了一个vbs脚本。为了保护它 - 我将其编码为vbe。如果我复制vbe代码并以字符串格式发送(例如,通过电子邮件发送)字符串到达​​已损坏。我应该如何处理代码,以便我可以安全地发送到其他来源?提前大大超过了!

我在HTA中创建了这个工具,以解码一些带有扩展名VBE的编码文件(通常这些文件是通过USB传播的病毒)到我的USB密钥和同事的USB中找到的VBS文件。
