![]() ![]() If we don't want this padding, we can use the withoutPadding() method on the encoder. String encodedStr = Base64.getEncoder().withoutPadding().encodeToString(bytesToEncode) //encoding without paddingīase64 class handles URL encoding and decoding by using the URL and Filename safe Base64 Alphabet. We can use the getUrlEncoder() method to obtain a Base64 URL encoder. Then, we can use the encodeToString() method as we did in the previous section. Similarly, we have a getUrlDecoder() method that returns a URL decoder. String decodedUrl = new String(decodedUrlBytes) ("Encoded URL: " encodedUrl) īyte decodedUrlBytes = Base64.getUrlDecoder().decode(encodedUrl) String encodedUrl = Base64.getUrlEncoder().encodeToString(urlToEncode.getBytes()) Again, we can use the decode() method with this decoder. ("Decoded URL: " decodedUrl) Įncoded URL: aHR0cHM6Ly9nby5qYXZhLz9pbnRjbXA9Z29qYXZhLWJhbm5lci1qYXZhLWNvbQ=ĭecoded URL: Base64 MIME Encoding and Decoding MIME stands for Multipurpose Internet Mail Extension, and the Base64 class uses the Base64 Alphabet for its encoding and decoding operations. In the encoded output, each line contains a maximum of 76 characters.Įach line ends with a carriage return( \r) followed by a linefeed( \n) as the line separator. Note that no line separator is present at the end of the encoded string. String mimeEncodedStr = Base64.getMimeEncoder().encodeToString(bytes) We can use the getMimeEncoder() and the encodeToString() methods for the encoding. ![]() Java provides a class Base64 to deal with encryption. You can encrypt and decrypt your data by using provided methods. You need to import 64 in your source file to use its methods. This class provides three different encoders and decoders to encrypt information at each level. ![]() You can use these methods at the following levels. It uses the Base64 alphabet specified by Java in RFC 4648 and RFC 2045 for encoding and decoding operations. It uses the Base64 alphabet specified by Java in RFC 4648 for encoding and decoding operations. The encoder does not add any line separator character. The decoder rejects data that contains characters outside the base64 alphabet. It uses the Base64 alphabet as specified in RFC 2045 for encoding and decoding operations. The encoded output must be represented in lines of no more than 76 characters each and uses a carriage return '\r' followed immediately by a linefeed '\n' as the line separator. No line separator is added to the end of the encoded output. All line separators or other characters not found in the base64 alphabet table are ignored in decoding operation. ![]()
