Fast Base64 Encoder

Boost your application today!

This library provides a pure java encoder for the Base64 algorithm with support for arrays, buffers, streams and channels. According to our benchmark, this is simply the fastest encoder. It is ten times faster then Sun internal encoder and twice faster than Apache Jakarta's one on big arrays of byte. The gain is even higher when working with small arrays.

Benchmark

It was conducted on Linux with Sun JRE 1.4.2_03 and Sun JRE 1.5.0beta2 in server mode. It included the following encoders:

  • sun.misc.BASE64Encoder (internal, versions 1.4 and 1.5)
  • Apache Jakarta Commons Codec Base64 Encoder (version 1.3)
  • ByteCream Fast Base64 Encoder (version 1.0)

Size of the
byte array		 Gain over

1K-100K+1157%+122%
100K-1M+894%+101%
1M-10M+697%+72%
10M-50M+829%+83%

Requirements

This library requires java 1.4 (or later). Contact us if you need it for java 1.3.

Adapters

We recommand to use directly our API. But if you can not change your application, we provide six adapters for:

  • Apache Axis Utils Base64 1.1: view the API, download the archive
  • Apache Jakarta Commons Codec Base64 1.3: view the API, download the archive
  • Apache Tomcat 5: view the API, download the archive
  • Apache Xerces 2: view the API, download the archive
  • Sun internal Apache Xerces: view the API, download the archive
  • Sun internal BASE64Encoder 1.4: view the API, download the archive

These adapters are free of charge but also come without warranty and support.

 Tips for upgrading your code: encoding a byte array

  • To replace
      new sun.misc.BASE64Encoder().encode(_data),
    use
      Base64Encoder.encodeWithLineSeparator
        (data,(data.length%57==0))    .

    The second agrument is needed due to the strange behavior of BASE64Encoder: a line separator is added to the final line only if this line has 76 characters.

  • To replace
      org.apache.commons.codec.binary.Base64.encode(data),
    use
      Base64Encoder.encodeWithCRLF(data,true).


 Example: encoding a file

(this code has been kept short for clarity)

import java.io.*;
import java.nio.channels.*;
import com.bytecream.codec.*;

public final class Encode64 {
  public static void main(String[] args)
    throws IOException {
    RandomAccessFile in  =new RandomAccessFile(args[0],"r");
    RandomAccessFile out =new RandomAccessFile(args[1],"rw");
    FileChannel      cin =in .getChannel();
    FileChannel      cout=out.getChannel();

    Base64EncoderNIO.encodeWithCRLF(cin,cout);

    cin .close();
    in  .close();
    cout.close();
    out .close();
  }
}
