Base64 is very popular for two way encoding and decoding of data. Here we have given an example of string to base64 and base64 to String using java.
Regular Base64 Uses "The Base64 Alphabet" as specified in Table 1 of RFC 4648 and RFC 2045 for encoding and decoding operation. The encoder does not add any line feed line separator character. The decoder rejects data that contains characters outside the base64 alphabet. Mime Base64. Base64 MIME Encode and Decode Tool. Use this free tool to turn binary data into text encode or text into binary decode. To allow binary data to be transmitted with textual data it must be encoded. An example of this is an attachment in an email. This is done via the MIME implementation of Base64. Base64 encode your data in a hassle-free way, or decode it into human-readable format. Base64 encoding schemes are commonly used when there is a need to encode binary data that needs be stored and transferred over media that are designed to deal with textual data. This is to ensure that the data remains intact without modification during transport.

This class implements a decoder for decoding byte data using the Base64 encoding scheme as specified in RFC 4648 and RFC 2045. The Base64 padding character '=' is accepted and interpreted as the end of the encoded byte data, but is not required.
This method first encodes all input bytes into a base64 encoded byte array and then constructs a new String by using the encoded byte array and the ISO-8859-1 charset. In other words, an invocation of this method has exactly the same effect as invoking new Stringencodesrc, StandardCharsets.ISO_8859_1. Base64 Decoding in Java. For every Base64 encoding variant implemented by the Base64 class, there is a decoder to turn the data back to its original form except without padding encoding. Base64 Basic Decoding. For Base64 basic decoding, just use the getDecoder to get a Base64.Decoder instance that decodes using the Basic type Base64. In this article, you'll learn how to Base64 decode any Base64 encoded data back to binary data. Java 8's Base64 API provides implementations for Base64 encoding and decoding as described in RFC 4648.

Base64是一种能将任意Binary资料用64种字元组合成字串的方法，而这个Binary资料和字串资料彼此之间是可以互相转换的，十分方便。在实际应用上，Base64除了能将Binary资料可视化之外，也常用来表示字串加密过后的内容。. The term Base64 originates from a specific MIME content transfer encoding. Base64 encoding schemes are commonly used when there is a need to encode binary data that needs to be stored and transferred over media that are designed to deal with textual data. This is to ensure that the data remain intact without modification during transport.
Decode and Encode Base64 data with this online base64 decoder. Base64 Encoding Scheme. While there are tons of encoding schemes available, we are going to see Base64 in our how to encode and decode a message in Java tutorial.

Java 8 introduced a new class called Base64 which contains convenience functions to Base64 encode a sequence of bytes and also decode a Base64 encoded string. Finally Java 8 includes a decent API for it in the java.util package. Here is a short introduction of this new API apparently it has a little more than the regular encode/decode API. The java.util.Base64 Utility Class. The entry point to Java 8's Base64 support is the java.util.Base64 class.
|Article shows how you can encode or decode Base64 within Java, java provide inbuilt function and having three variant, each of them are covered here. Encode String.

The decoder rejects data that contains characters outside the base64 alphabet. URL and Filename safe.
Since Java 1.8 developers can use the Base64.Encoder class to encode data to Base64. This class provides several methods for encoding byte data to Base64 using algorithms specified in RFC 4648 and RFC 2045. In addition, Java provides the Base64.Decoder class for decoding Base64 values to byte data. Example 1 encode string. Base64 Decoding in Java Rajeev Singh 4 mins.
