Package org.apache.commons.codec Description

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 three categories: Binary Encoders, Language Encoders, and Network Encoders.

Binary Encoders

org.apache.commons.codec.binary.Base64	Provides Base64 content-transfer-encoding as defined in RFC 2045	Production
org.apache.commons.codec.binary.Hex	Converts an array of bytes into an array of characters representing the hexadecimal values of each byte in order	Production

Language Encoders

Codec contains a number of commonly used language and phonetic encoders

org.apache.commons.codec.language.Soundex	Implementation of the Soundex algorithm.	Production
org.apache.commons.codec.language.Metaphone	Implementation of the Metaphone algorithm.	Production

Network Encoders

Codec contains network related encoders

org.apache.commons.codec.net.URLCodec

Implements the 'www-form-urlencoded' encoding scheme.
