org.apache.commons.codec.binary.Base64 Example
What is org.apache.commons.codec.binary.Base64 class? How to use org.apache.commons.codec.binary.Base64 class?
✍: FYIcenter.com
org.apache.commons.codec.binary.Base64 class is a Java class offered in commons-codec.jar that provides Base64 encoding and decoding as defined by RFC 2045.
Two commonly used static methods in org.apache.commons.codec.binary.Base64 class are:
1. The encoding method:
public static byte[] encodeBase64(byte[] binaryData) Encodes binary data using the base64 algorithm but does not chunk the output. Parameters: binaryData - binary data to encode Returns: byte[] containing Base64 characters in their UTF-8 representation.
2. The decoding method:
public static byte[] decodeBase64(byte[] base64Data) Decodes Base64 data into octets. Note: this method seamlessly handles data encoded in URL-safe or normal mode. Parameters: base64Data - Byte array containing Base64 data Returns: Array containing decoded data.
Here is a simple example of org.apache.commons.codec.binary.Base64 class:
// Copyright (c) 2016 FYIcenter.com import org.apache.commons.codec.binary.Base64; // Example of using the Base64 class public class Base64Example { public static void main(String[] args) throws Exception { System.out.println("encodeBase64() Example:"); String inputString = "Hello World"; byte[] inputBytes = inputString.getBytes("UTF8"); byte[] outputBytes = Base64.encodeBase64(inputBytes); String outputString = new String(outputBytes,"UTF8"); String expectedString = "SGVsbG8gV29ybGQ="; System.out.println(" Input string: "+inputString); System.out.println(" Encoded string: "+outputString); System.out.println(" Expected string: "+expectedString); System.out.println("decodeBase64() Example:"); inputString = "SGVsbG8gV29ybGQ="; inputBytes = inputString.getBytes("UTF8"); outputBytes = Base64.decodeBase64(inputBytes); outputString = new String(outputBytes,"UTF8"); expectedString = "Hello World"; System.out.println(" Input string: "+inputString); System.out.println(" Encoded string: "+outputString); System.out.println(" Expected string: "+expectedString); } }
You can compile and run the above example in a command window as shown below:
C:\fyicenter>\local\jdk-1.8.0\bin\javac -cp C:\local\commons-codec-1.10\commons-codec-1.10.jar Base64Example.java C:\fyicenter>\local\jdk-1.8.0\bin\java -cp .;C:\local\commons-codec-1.10\commons-codec-1.10.jar Base64Example encodeBase64() Example: Input string: Hello World Encoded string: SGVsbG8gV29ybGQ= Expected string: SGVsbG8gV29ybGQ= decodeBase64() Example: Input string: SGVsbG8gV29ybGQ= Encoded string: Hello World Expected string: Hello World
