本文整理了Java中org.bouncycastle.util.encoders.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：org.bouncycastle.util.encoders.Base64
类名称：Base64

Base64介绍

[英]Utility class for converting Base64 data to bytes and back again.
[中]用于将Base64数据转换为字节并再次转换回字节的实用程序类。

代码示例

private byte[] decode(String encoded) throws DecoderException {
  if (this.encoding.equalsIgnoreCase("HEX")) {
    return Hex.decodeHex(encoded.toCharArray());
  } else {
    return Base64.decode(encoded);
  }
}
