![]() ![]() UnsupportedEncodingException import java. Then, we will use the decode() method of the decoder. ![]() In addition, Java provides the Base64.Decoder class for decoding Base64 values to byte data. This class provides several methods for encoding byte data to Base64 using algorithms specified in RFC 4648 and RFC 2045. The decoder ignores all line separators and other characters not found in the basic base64 alphabet. To decode an encoded string, we will use Base64.Decoder returned by the getDecoder() method. Since Java 1.8 developers can use the Base64.Encoder class to encode data to Base64. ![]() Each line (except the last line) is separated from the next line via a carriage return (\r) followed by a linefeed (\n). The encoded output is organized into lines of no more than 76 characters. MIME enforces a limit on line length of Base64 encoded data. MIME: The MIME variant uses the Basic Base64 alphabet ( A-Za-z0-9 /). The decoder rejects data that contains characters outside A-Za-z0-9-_. The Base64 class is part of java.util class that provides static methods for the Base64 encoding and decoding scheme. This class provides several methods for decoding Base64 to byte data. URL and Filename Safe: It is same as the Basic Base64 encoding except that is replaced by - and / is replaced by _ to make the output URL and filename safe. Since Java 1.8 developers can use the Base64.Decoder class to decode Base64 values. Which Java library provides base64 encoding/decoding byte message hello world.getBytes(StandardCharsets.UTF8) String encoded Base64.getEncoder(). The decoder rejects data that contains characters outside this set. The algorithm converts the input to a set of characters containing A-Z, a-z, 0-9, and /. Basic: This is the standard Base64 encoding defined in the RFC 4648.We will then take the Base64 encoded String value and will decode it back into original String. Java 8’s Base64 API contains implementations for all the Base64 encoding and decoding variants described in the official RFC 4648.įollowing variants of Base64 encoding and decoding is supported - In this short Java programming tutorial I am going to share with you how to take a String value and Base64 encode it. In this article, you’ll learn how to Base64 decode any Base64 encoded text back to binary data. ![]()
