Class Base16

java.lang.Object
org.apache.commons.codec.binary.BaseNCodec
org.apache.commons.codec.binary.Base16
All Implemented Interfaces:
BinaryDecoder, BinaryEncoder, Decoder, Encoder

public class Base16 extends BaseNCodec
Provides Base16 encoding and decoding.

This class is thread-safe.

This implementation strictly follows RFC 4648, and as such unlike the Base32 and Base64 implementations, it does not ignore invalid alphabet characters or whitespace, neither does it offer chunking or padding characters.

The only additional feature above those specified in RFC 4648 is support for working with a lower-case alphabet in addition to the default upper-case alphabet.

Since:
1.15
