This class implements a decoder for decoding byte data using the Base64 encoding scheme as specified in RFC and RFC static class, Base Encodes all bytes from the specified byte array using the Base64 encoding scheme, writing the resulting bytes to the given output byte array, starting at offset 0. With Java 8, Base64 has finally got its due. Java 8 now has inbuilt encoder and decoder for Base64 encoding. In Java 8, we can use three types of Base

Worse, code compiled for Java 7 using javax.

Java 8 – Base64

I used Apache Commons as the solution suggested by including: The decoder rejects data that contains characters outside the base64 alphabet. Delete those imports and let Eclipse import gase64binary proper Commons classs for you. I would also choose Java 8’s class is possible.

The returned byte array is of the length of the resulting bytes. But again, both of them are shown as errors. Marko Topolnik k 19 No line separator is present to the end of the encoded output.


If you are using Spring framework at least version 4. Unless otherwise noted, passing a null argument to a method nase64binary this class will cause a NullPointerException to be thrown.

How do I decode a Base64 encoded binary? | Kode Java

Encoder getEncoder Returns a Base A newly-allocated byte array containing the resulting encoded bytes. Encoder getUrlEncoder Returns a Base Eventually the Base64 class from Java 8 will be the way to go. Decoder getDecoder Returns a Base Jakarta Commons provides its own implementation of base64 codecs, which of course reside in a different package. A newly-allocated byte buffer containing the encoded bytes.

Encoder getUrlEncoder Returns a Base Decoder that decodes using the MIME type base64 decoding scheme. Email Required, but never shown. It is the responsibility of the invoker of this method to make sure the output byte array dst has enough space for encoding all bytes from gase64binary input byte array.

Encoder getEncoder Returns a Base Base64bianry that encodes using the Basic type base64 encoding scheme. But if you have to target Java 7 in the meantime, this solution is nice since it does not rely on external libraries. That documentation contains more detailed, developer-targeted descriptions, with conceptual overviews, definitions of terms, workarounds, and working code examples.


Encoder that encodes using the MIME type base64 encoding base64bonary. This is the best answer if you’re developing for Android and you can’t use Java 8. First, import it as you normally do: Like that you can get code examples. Kirby 9, 6 59 DatatypeConverter printBase64Binary method For example: Bae64binary And then change your Class to use the Base64 class.

They are not part of the public API; they may be changed, removed or whatever without notice. Maybe someone could comment as to why this is, but I found my workaround as an acceptable compromise.

Decoder getUrlDecoder Returns a Base I found a similar post here. The number of bytes written to the output byte array Throws: The encoding scheme of this encoder instance is unaffected by this invocation.

Works under Java 7 and 8, but not Java 9. Decoder getMimeDecoder Returns a Base No line separator is added to the end of the encoded output.
