Apache HttpClient 5.3 · org.apache.hc.client5.http.utils.Base64

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.

This class is intended as in interim convenience. Any new code should use `java.util.Base64` directly.

Constructor Summary

Access	Constructor and Description
public	Base64() Return an instance of the Base64 codec that use the regular Base64 alphabet (as opposed to the URL-safe alphabet).
public	Base64(final int lineLength) Creates a Base64 codec used for decoding and encoding in URL-unsafe mode.

Modifier and Type	Method and Description
public byte[]	decode(final byte[] base64) Decode Base64-encoded bytes to their original form, using specifications from this codec instance
public byte[]	decode(final String base64) Decode a Base64 String to its original form, using specifications from this codec instance
public static byte[]	decodeBase64(final byte[] base64) Decodes Base64 data into octets.
public static byte[]	decodeBase64(final String base64) Decodes a Base64 String into octets.
public byte[]	encode(final byte[] value) Encode bytes to their Base64 form, using specifications from this codec instance
public static byte[]	encodeBase64(final byte[] base64) Encodes binary data using the base64 algorithm but does not chunk the output.
public static String	encodeBase64String(final byte[] bytes) Encodes binary data using the base64 algorithm but does not chunk the output.

Base64	back to summary
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	back to summary
public Base64(final 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.

Base64

public Base64(final 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.
