Examples of Base64

aQute.base64.Base64
com.alibaba.fastjson.util.Base64
A very fast and memory efficient class to encode and decode to and from BASE64 in full accordance with RFC 2045.

On Windows XP sp1 with 1.4.2_04 and later ;), this encoder and decoder is about 10 times faster on small arrays (10 - 1000 bytes) and 2-3 times as fast on larger arrays (10000 - 1000000 bytes) compared to sun.misc.Encoder()/Decoder().

On byte arrays the encoder is about 20% faster than Jakarta Commons Base64 Codec for encode and about 50% faster for decoding large arrays. This implementation is about twice as fast on very small arrays (< 30 bytes). If source/destination is a String this version is about three times as fast due to the fact that the Commons Codec result has to be recoded to a String from byte[], which is very expensive.

This encode/decode algorithm doesn't create any temporary arrays as many other codecs do, it only allocates the resulting array. This produces less garbage and it is possible to handle arrays twice as large as algorithms that create a temporary array. (E.g. Jakarta Commons Codec). It is unknown whether Sun's sun.misc.Encoder()/Decoder() produce temporary arrays but since performance is quite low it probably does.

The encoder produces the same output as the Sun one except that the Sun's encoder appends a trailing line separator if the last character isn't a pad. Unclear why but it only adds to the length and is probably a side effect. Both are in conformance with RFC 2045 though.
Commons codec seem to always att a trailing line separator.

Note! The encode/decode method pairs (types) come in three versions with the exact same algorithm and thus a lot of code redundancy. This is to not create any temporary arrays for transcoding to/from different format types. The methods not used can simply be commented out.

There is also a "fast" version of all decode methods that works the same way as the normal ones, but har a few demands on the decoded input. Normally though, these fast verions should be used if the source if the input is known and it hasn't bee tampered with.

de.innovationgate.utils.Base64
General purpose class to convert bytes to Base64 encoded strings or vice versa. Is able to use the "traditional" encoding pattern (using + and / characters that are not safe in URLs) and the "web-safe" encoding (using - and _ instead).

Provides Base64 encoding and decoding as defined by RFC 2045.
This class is taken from the Apache commons-codec, and adjusted to fit the Wicket framework's needs, especially external dependencies have been removed.

This class implements section 6.8. Base64 Content-Transfer-Encoding from RFC 2045 Multipurpose Internet Mail Extensions (MIME) Part One: Format of Internet Message Bodies by Freed and Borenstein.

This class implements section 6.8. Base64 Content-Transfer-Encoding from RFC 2045 Multipurpose Internet Mail Extensions (MIME) Part One: Format of Internet Message Bodies by Freed and Borenstein.

The class can be parameterized in the following manner with various constructors:
- URL-safe mode: Default off.
- Line length: Default 76. Line length that aren't multiples of 4 will still essentially end up being multiples of 4 in the encoded data.
- Line separator: Default is CRLF ("\r\n")
Since this class operates directly on byte streams, and not character streams, it is hard-coded to only encode/decode character encodings which are compatible with the lower 127 ASCII chart (ISO-8859-1, Windows-1252, UTF-8, etc).

This class is thread-safe.
