Good news for Base64

Plans to include Base64 API in OpenJDK

As proposals flood in for JDK 8, an old problem is finally addressed.

Progress behind Oracle’s Java 8 open source implementation,
Open JDK is
motoring on into 2012, with numerous JDK Enhancement Proposals
cropping up. But one recent suggestion will finally tackle the long
overdue issue of a standard API for Base64 encoding and

Oracle’s Alan Bateman made the submission back in November but
it appears that it will become part of the next full stable release
of the JDK. Bateman stated the motivation behind proposing a
standardised and fully supported Base64 API:

Base64 encoding
 are frequently used to encode binary/octet
sequences that are transmitted as textual data. It is commonly used
by applications using Multipurpose Internal Mail Extensions (MIME),
encoding passwords for HTTP headers, message digests, etc.

The JDK is long overdue a standard API for Base64 encoding and
decoding. It has been frequently requested by developers for many
years, many resorting to using JDK private and unsupported classes
as sun.misc.BASE64Encoder andsun.misc.BASE64Decoder.

The JDK itself has several internal
implementations: java.util.prefs.Base64,, to name a few. A
standard API would allow these sorts of implementations to be

The plan of action – to define a simple API, likely
in java.util for encoding and decoding then assess which
of the unsupported versions are no longer needed with the API in
place. Of course, this would incur a heavy amount of testing to get
it ready for JDK 8.

Keeping track of all the proposals that could be set to
feature in OpenJDK: JDK 8 is a wise move – there are some
intriguing propositions. The two key projects – Lambda and Jigsaw
are also worth monitoring – we may well see some movement there
incredibly soon.
