Class Base85Codec

java.lang.Object

cn.hutool.core.codec.Base85Codec

All Implemented Interfaces:

Decoder<byte[],byte[]>, Encoder<byte[],byte[]>, Serializable

public class Base85Codec
extends Object
implements Encoder<byte[],byte[]>, Decoder<byte[],byte[]>, Serializable

Base85(Ascii85)编码解码实现
相比Base64，Base85使用更多的可打印字符，编码后体积更小（膨胀率约25%）
支持标准RFC1924风格和Z85(ZMQ)风格
