不使用“+/="的 base64 编码；(加号或等于)字符? [英] base64 encoding that doesn't use "+/=" (plus or equals) characters?

问题描述

我需要对一个大约 1000 个字符的字符串进行编码，该字符串可以是任何字节值 (00-FF).我不想使用十六进制，因为它不够密集.据我所知，base64 的问题在于它包含 +/和 =，这是我在我的应用程序中无法容忍的字符.

I need to encode a string of about 1000 characters that can be any byte value (00-FF). I don't want to use Hex because it's not dense enough. the problem with base64 as I understand it is that it includes + / and = which are characters I can not tolerate in my application.

有什么建议吗?

推荐答案

正如 Ciaran 所说，base64 实现起来并不难——但你可能想看看现有的库，它允许你指定一组自定义的要使用的字符.我很确定那里有很多，但你没有指定你需要哪个平台.

As Ciaran says, base64 isn't terribly hard to implement - but you may want to have a look for existing libraries which allow you to specify a custom set of characters to use. I'm pretty sure there are plenty out there, but you haven't specified which platform you need this for.

基本上，您只需要可接受的 65 个 ASCII 字符 - 最好除了换行符.

Basically, you just need 65 ASCII characters which are acceptable - preferably in addition to line breaks.
