## 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. | Production
