@Internal public class Base64 extends java.lang.Object
Provide implementations of the Base64 conversion methods from Commons Codec, delegating to the Java Base64 implementation.Only the features currently used by HttpClient are implemented here rather than all the features of Commons Codec.
Notes:
- Commons Codec accepts null inputs, so this is also accepted here. This is not done in the Java 8 implementation
- Decoding invalid input returns an empty value. The Java 8 implementation throws an exception, which is caught here
- Commons Codec decoders accept both standard and url-safe variants of input. As this is not a requirement for HttpClient, this is NOT implemented here.

Base64
public Base64()
Return an instance of the Base64 codec that use the regular Base64 alphabet (as opposed to the URL-safe alphabet). Note that unlike the Commons Codec version, thus class will NOT decode characters from URL-safe alphabet.
-
Base64
public Base64(int lineLength)
Creates a Base64 codec used for decoding and encoding in URL-unsafe mode.As HttpClient never uses a non-zero length, this feature is not implemented here.
