Encoding and Decoding
Security Testing - Encoding and Decoding
What is Encoding and Decoding?
编码是将信函、编号和其他特殊特性等一系列特性纳入高效传输的专门格式的过程。
下降是将编码格式重新转换为原特性序列的过程。 这完全不同于通常错误解释的加密。
编码和编码在数据通信和储存中使用。 如果使用NOT来运输敏感信息,则进行编码。
URL Encoding
URLs只能使用ASCII型特性组装在互联网上,在有些情况下,除了ASCII型特性外,还包含特殊特性,需要加以编码。 URLs并不包含空间,而是用附加(+)签字或用月替换。
ASCII Encoding
Browser(客户方面)将根据网页使用的特性分类编码输入,而以超文本5表示的违约特性是UTF-8。
下表显示了ASCII特性及其平等文号的象征,最后可以将其替换为URL,然后将其转至服务器。
