Base64 (SAVOT API)

java.lang.Object
- cds.savot.binary.Base64

public final class Base64
extends java.lang.Object

Lets encoding and decoding String with the Base64.

Note: To encode/decode stream of data, you can also use Base64InputStream and Base64OutputStream.

Examples:

 public final static void main(final String[] args) throws Exception {
        String message = "Hi ! If you can read this, the Base64 encoding/decoding has completely worked ! Well done ;-) !";
 
        System.out.println("ORIGINAL MESSAGE:\n\""+message+"\"");
 
        String encoded, decoded;
 
        System.out.println("\nEncoding....");
        encoded = Base64.encodeStr(message);
        System.out.println("ENCODED MESSAGE:\n\""+encoded+"\"");
 
        System.out.println("\nDecoding....");
        decoded = Base64.decodeStr(encoded);
        System.out.println("DECODED MESSAGE:\n\""+decoded+"\"");
 }
