How To Encode Decode String Inwards Coffee Base64 Encoding

Encoding in addition to Decoding of String inward Java using base64 are extremely slowly if y'all are using Apache common code opened upwards source library. it provides convenient static utility method Base64.encodeBase64(byte[]) in addition to Base64.decodeBase64(byte []) for converting binary information into base64 encoded binary Stream in addition to and therefore decoding dorsum from encoded information inward base64 encoding mechanism. Many times nosotros ask to encode sensitive information hold upwards it binary String  format transferring over a socket or transferring or storing information inward XML files. Though in that place are other opened upwards source libraries available which supply back upwards to encode whatever String into base64 e.g. MimeUtil from javax.mail package simply Apache common codec parcel is really handy in addition to doesn't add together a lot of extra stuff. its API is every bit good really keen in addition to clean. In this article, nosotros volition encounter how to encode in addition to decode String into base64 encoding.

Base64 Encoding Algorithm

String using an algorithm which uses 64 printable characters to supercede each grapheme inward an master string inward an algorithmic sequence therefore that it tin hold upwards decoded later. Why to char array is preferred over String for storing password in addition to Why String is immutable inward Java, which y'all may like.

Encoding & Decoding String into Base64 Java

Here is a quick example of encoding in addition to decoding of String inward base64 encoding algorithm. nosotros volition get-go encode String yesteryear converting it into a byte array in addition to and therefore passing downwardly to Base64.encodeBase64(byte[]) which encodes byte array

as per base64 encoding algorithm in addition to returns in addition to encoded byte array, which tin hold upwards converted into String. inward Later

half, nosotros volition decode the String yesteryear calling Base64.decodeBase64(byte[]) method.

import org.apache.commons.codec.binary.Base64;

/**

 * Java programme to encode in addition to decode String inward Java using Base64 encoding algorithm

 * @author http://javarevisited.blogspot.com

 */

public degree Base64EncodingExample{

    populace static void main(String args[]) throws IOException {

        String orig = "original String earlier base64 encoding inward Java";

        //encoding  byte array into base of operations 64

        byte[] encoded = Base64.encodeBase64(orig.getBytes());     

      

        System.out.println("Original String: " + orig );

        System.out.println("Base64 Encoded String : " + novel String(encoded));

      

        //decoding byte array into base64

        byte[] decoded = Base64.decodeBase64(encoded);      

        System.out.println("Base 64 Decoded  String : " + novel String(decoded));

    }

}

Output:

Original String: master String earlier base64 encoding inward Java

Base64 Encoded String : b3JpZ2luYWwgU3RyaW5nIGJlZm9yZSBiYXNlNjQgZW5jb2RpbmcgaW4gSmF2YQ==

Base 64 Decoded  String : master String earlier base64 encoding inward Java

Dependency

In club to execute this Base64 Encoding Example inward Java, y'all ask to download in addition to add together commons-codec-1.2.jar into your application classpath. if y'all are using Maven for managing your projection dependency y'all tin include the following

dependency inward pom.xml:

<dependency>

  <groupId>commons-codec</groupId>

  <artifactId>commons-codec</artifactId>

  <version>20041127.091804</version>

</dependency>

This is really uncomplicated in addition to construct clean base64 encoding instance inward Java simply serves the purpose. That's all inward how to

encode Java String into Base64 encoding in addition to how to decode Java String. allow me know if y'all confront whatever issue.
