Codec – Commons Codec

User guide

Codec is comprised of a set of utilities and a simple framework for encoding and decoding text and binary data.

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

Base32	Provides Base32 encoding and decoding as defined by RFC 4648
Base32InputStream	Provides Base32 encoding and decoding in a streaming fashion (unlimited size).
Base64	Provides Base64 encoding and decoding as defined by RFC 2045
Base64InputStream	Provides Base64 encoding and decoding in a streaming fashion (unlimited size).
BinaryCodec	Converts between byte arrays and strings of "0"s and "1"s.
Hex	Converts hexadecimal Strings.

DigestUtils

Simplifies common MessageDigest tasks and provides GNU libc crypt(3) compatible password hashing functions.

Caverphone 1.0	Encodes a string into a Caverphone 1.0 value.
Caverphone 2.0	Encodes a string into a Caverphone 2.0 value.
Cologne Phonetic	Encodes a string into a Cologne Phonetic value.
Double Metaphone	Encodes a string into a double metaphone value.
Metaphone	Encodes a string into a Metaphone value.
Refined Soundex	Encodes a string into a Refined Soundex value.
Soundex	Encodes a string into a Soundex value.

BCodec	Identical to the Base64 encoding defined by RFC 1521 and allows a character set to be specified.
QCodec	Similar to the Quoted-Printable content-transfer-encoding defined in RFC 1521 and designed to allow text containing mostly ASCII characters to be decipherable on an ASCII terminal without decoding.
QuotedPrintableCodec	Codec for the Quoted-Printable section of RFC 1521 .
URLCodec	Implements the `www-form-urlencoded` encoding scheme, also misleadingly known as URL encoding.
