本文整理了Java中es.gob.afirma.core.misc.Base64类的一些代码示例，展示了Base64类的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Base64类的具体详情如下：
包路径：es.gob.afirma.core.misc.Base64
类名称：Base64

Base64介绍

[英]Encodes and decodes to and from Base64 notation.

Homepage: http://iharder.net/base64.

Example:
String encoded = Base64.encode( myByteArray );
byte[] myByteArray = Base64.decode( encoded );

The options parameter, which appears in a few places, is used to pass several pieces of information to the encoder. In the "higher level" methods such as encodeBytes( bytes, options ) the options parameter can be used to indicate such things as not inserting linefeeds, and encoding using the URL-safe and Ordered dialects.

Note, according to RFC3548, Section 2.1, implementations should not add line feeds unless explicitly told to do so. I've got Base64 set to this behavior now, although earlier versions broke lines by default.

The constants defined in Base64 can be OR-ed together to combine options, so you might make a call like this:
String encoded = Base64.encodeBytes( mybytes, Base64.DO_BREAK_LINES );

to compress the data before encoding it and then making the output have newline characters.

Also...
String encoded = Base64.encodeBytes( crazyString.getBytes() );

I am placing this code in the Public Domain. Do with it as you will. This software comes with no guarantees or warranties but with plenty of well-wishing instead! Please visit http://iharder.net/base64 periodically to check for updates or to contribute improvements.
[中]对Base64符号进行编码和解码。
主页：http://iharder.net/base64。
例子：
String encoded = Base64.encode( myByteArray );
byte[] myByteArray = Base64.decode( encoded );
选项参数出现在几个地方，用于将多条信息传递给编码器。在“更高级别”的方法中，例如encodeBytes（bytes，options），options参数可用于指示不插入换行符，以及使用URL安全和有序方言进行编码。
注意，根据RFC3548，第2.1节，除非明确要求添加换行符，否则实现不应该添加换行符。我现在已经将Base64设置为这种行为，尽管早期版本在默认情况下会中断。
Base64中定义的常量可以合并或合并在一起以组合选项，因此您可以进行如下调用：
String encoded = Base64.encodeBytes( mybytes, Base64.DO_BREAK_LINES );
在编码数据之前压缩数据，然后使输出具有换行符。
而且
String encoded = Base64.encodeBytes( crazyString.getBytes() );
我将此代码置于公共域中。你想怎么做就怎么做。这个软件没有任何保证或保证，但却有很多美好的愿望！请定期访问http://iharder.net/base64，检查更新或作出改进。
