Decoding a String using Base64 on Linux Now that we have shown you how to encode a string using base64 on Linux, let us move on to decoding the string. To get the base64 tool to decode a string or file, you will need to pass in the “-d” or “--decode” option. ...
Base64 encoding uses printable characters to encode binary data. This enables another interesting use case: You can encode multiline files into Base64 strings. While rare, you may come across software or scripts that accept an entire configuration file as a Base64-encoded string. ...
很多语言都有内置的 base64 encode 以及 decode 函数。比如 PHP 里有base64_encode()函数: 复制代码<?php$file="1.gif";// 文件路径if($fp=fopen($file,"rb",0)) {$binary=fread($fp,filesize($file));// 文件读取fclose($fp);$base64=base64_encode($binary);// 转码echo$base64;// 显示base...
2回答 对于base64_codec,首选str.encode('base64_codec')还是base64.b64encode(str)? 、 在Python库中,有用于在Base64上工作的base64模块。同时,如果你想编码一个字符串,有一个base64的编解码器,也就是str.encode('base64_encode')。 浏览2提问于2013-04-25得票数 4 回答已采纳 ...
