Java Base64

Java 8 Basic Base64. The basic encoder keeps things simple and encodes the input as is, without any line separation. The output is mapped to a set of characters in A-Za-z0-9+/ character set, and the decoder rejects any character outside of this set. Let's first encode a simple String

Java Base64 Encoding and Decoding Baeldun

Base64 is a binary-to-text encoding scheme that represents binary data in a printable ASCII string format. In this article, you'll learn how to Base64 encode any arbitrary text in Java using the Base64 API that was introduced in Java 8. The Java 8 Base64 API supports three different variants of Base64 encoding as described in RFC 4648 and RFC 2045 Java 8 - Base64 Simple − Output is mapped to a set of characters lying in A-Za-z0-9+/. The encoder does not add any line feed in output,... URL − Output is mapped to set of characters lying in A-Za-z0-9+_. Output is URL and filename safe. MIME − Output is mapped to MIME friendly format. Output is. Java Base64 Encode and Decode. Java provides a class Base64 to deal with encryption. You can encrypt and decrypt your data by using provided methods. You need to import java.util.Base64 in your source file to use its methods. This class provides three different encoders and decoders to encrypt information at each level. You can use these methods at the following levels public static class Base64.Encoder extends Object This class implements an encoder for encoding byte data using the Base64 encoding scheme as specified in RFC 4648 and RFC 2045. Instances of Base64.Encoder class are safe for use by multiple concurrent threads

java.util.Base64.Decoder. Enclosing class: Base64. public static class Base64.Decoder extends Object. This class implements a decoder for decoding byte data using the Base64 encoding scheme as specified in RFC 4648 and RFC 2045. The Base64 padding character '=' is accepted and interpreted as the end of the encoded byte data, but is not required First, import it as you normally do: import java.util.Base64; Then use the Base64 static methods as follows: byte [] encodedBytes = Base64.getEncoder ().encode (Test.getBytes ()); System.out.println (encodedBytes + new String (encodedBytes)); byte [] decodedBytes = Base64.getDecoder ().decode (encodedBytes); System.out.println (decodedBytes .

As of Java 8, there is an officially supported API for Base64 encoding and decoding. In time this will probably become the default choice. The API includes the class java.util.Base64 and its nested classes. It supports three different flavors: basic, URL safe, and MIME Java 8's Base64 API contains implementations for all the Base64 encoding and decoding variants described in the official RFC 4648. Following variants of Base64 encoding and decoding is supported - Basic: This is the standard Base64 encoding defined in the RFC 4648 For many years, java has provided support for base 64 via a non-public class (therefore non-usable) java.util.prefs.Base64 an undocumented class sun.misc.BASE64Encoder.
