Package org.apache.commons.codec

Interfaces and classes used by the various implementations in the sub-packages.

Definitive implementations of commonly used encoders and decoders.

Codec is currently comprised of a modest set of utilities and a simple framework for String encoding and decoding in the following packages:

• Binary codecs.
• Command line utility.
• Digests and hashers
• Common language and phonetic encoders.
• Beider-Morse codec.
• Network codecs.
