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. Static Base64.Encoder getMimeEncoder(int lineLength, byte lineSeparator) 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. ![]() By and large, the padding character ensures that the length of Base64 value is a multiple of 4 bytes and it is always appended at the end of the output. That is, the equal sign does not own an index and is not involved in the encoding of data. decoders MAY chose to reject an encoding if the pad bits have not been set to zero. In addition to these characters, the equal sign ( ) is used for padding. 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. Interpretation of Non-Alphabet Characters in Encoded Data. 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. The general rule is to choose a set of 64 characters that is both 1) part of a subset common to most encodings, and 2) also printable. Design The particular choice of characters to make up the 64 characters required for Base64 varies between implementations. Java 8 now has inbuilt encoder and decoder for Base64 encoding. The Base64 term originates from a specific MIME-content transfer encoding. There is another encoding scheme called Base64 Encode.With Java 8, Base64 has finally got its due. Because sending the encoded data from Application A to B would cause many problems because Application B would not interpret some of the data sent from Application A correctly. The whole point of base64 is to provide a safe way of converting arbitrary binary data into a text format which can be reliably embedded in other text. Every character in the output is printable ASCII text. The best solution is to send the data from Application A to C. Base64 encoding is applied to binary data (a sequence of bytes, or octets if you want to be even more picky), and the result is text. ![]() That can potentially encode 128 characters (That is just a small fraction of the UTF-8 encoding scheme).Īpplication C is using the same encoding scheme as application A (UTF-8 encoding scheme). That can potentially encode 2,164,864 characters.Īpplication B is using the ASCII encoding scheme. Suppose there are three applications, A, B, and C.Īpplication A is using the X encoding scheme.Īpplication B is using the Y encoding scheme, which is a subset of the X encoding scheme.Īpplication C is using the same encoding scheme as application A.Īpplication A is using the UTF-8 encoding scheme. Encoding is the simple process of converting the information or instruction into some specific form.
