The default chunk size of the encoded text is 76 characters. To encode a regular text to base64, type in the first box and click the Encode button. ("Original String: " + new String(base64decodedBytes, "utf-8")) īase64encodedString = Base64.getUrlEncoder(). Base64 is a protocol that maps any content - binary or plain text - to readable characters. ("Base64 Encoded String (Basic) :" + base64encodedString) īyte base64decodedBytes = Base64.getDecoder().decode(base64encodedString) "TutorialsPoint?java8".getBytes("utf-8")) The encoder does not add any line feed in output, and the decoder rejects any character. String base64encodedString = Base64.getEncoder().encodeToString( Simple Output is mapped to a set of characters lying in A-Za-z0-9+/. Import java.io.UnsupportedEncodingException This class inherits methods from the following class −Ĭreate the following Java program using any editor of your choice in say C:/> JAVA. Returns a Base64.Encoder that encodes using the URL and Filename safe type base64 encoding scheme. Returns a Base64.Decoder that decodes using the URL and Filename safe type base64 encoding scheme. Returns a Base64.Encoder that encodes using the MIME type base64 encoding scheme with specified line length and line separators. This character set supported 256 different character codes. ISO-8859-1 was the default character set for HTML 4.

Static Base64.Encoder getMimeEncoder(int lineLength, byte lineSeparator) ASCII was the first character encoding standard. Returns a Base64.Encoder that encodes using the MIME type base64 encoding scheme. Returns a Base64.Decoder that decodes using the MIME type base64 decoding scheme. Returns a Base64.Encoder that encodes using the Basic type base64 encoding scheme. Returns a Base64.Decoder that decodes using the Basic type base64 encoding scheme. This class implements an encoder for encoding byte data using the Base64 encoding scheme as specified in RFC 4648 and RFC 2045. This class implements a decoder for decoding byte data using the Base64 encoding scheme as specified in RFC 4648 and RFC 2045. No line separator is present to the end of the encoded output. Output is represented in lines of no more than 76 characters each, and uses a carriage return '\r' followed by a linefeed '\n' as the line separator. MIME − Output is mapped to MIME friendly format. URL − Output is mapped to set of characters lying in A-Za-z0-9+_. The encoder does not add any line feed in output, and the decoder rejects any character other than A-Za-z0-9+/. Simple − Output is mapped to a set of characters lying in A-Za-z0-9+/. In Java 8, we can use three types of Base64 encoding. Java 8 now has inbuilt encoder and decoder for Base64 encoding. Hence, one can see that the Base64 encoding is not encryption but just a way to transform any given data into a stream of printable characters which can be transmitted over network.With Java 8, Base64 has finally got its due.

Value Encoding Value Encoding Value Encoding Value Encoding Such non-text(binary) represenation is encoded in textual format such that each ASCII character takes one out of sixty four( A-Z, a-z, 0-9, + and /) possible character set. During data transmission, data can be textual or non-text(binary) like image, video, file etc.Īs we know, during transmission only a stream of data(textual/printable characters) can be sent or received, hence we need a way encode non-text data like image, video, file.īinary and ASCII representation of non-text(image, video, file) is easily obtainable.
