cpprestsdk Microsoft project for cloud-based client-server communication OpenSignX在Java 8中，Base64编码已经成为Java类库的标准。 Java 8 内置了 Base64 编码的编码器和解码器。 Base64工具类提供了一套静态方法获取下面三种BASE64编解码器：There is a non-public class in Java 1.4+ called java. Java Base64 The Java Base64 library enables your Java application to encode and decode base64 strings and streams. Some projects: ThreadWorker, Xmlizable, Base64, Tabu Search. It provides a set of static factory methods used to obtain one of the three Base64 encodes and decoders: A collection of open source and public domain software for Java, XML, and Cocoa, primarily.

The entry point to Java 8's Base64 support is the 64 class.

The following code snippet shows how to convert Base64 string to a JPG or PNG image using Java:

Therefore, you need to follow these steps for the conversion: Save the data in a TXT file because of a long string.

Besides that, you have the original byte. The output is a String, so the output needs 4/3*sizeof (char) bytes for the output String = 8/3. As you understand, Base64 encoding requires 4/3 of the input array length for the output.

This time will will run the JVM with -Xmx8G key to see the actual memory consumption.

The undocumented classes 64Encoder and 64Decoder should not be used ( explanation ). There is no Base64 encoder/decoder in the standard Java SDK class library up to Java 7.

Base64Coder is a fast and compact Base64 encoder/decoder class.
