Codec consists 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. |
WARNING: Some of the functions in this package might not be suitable for cryptography, or are no longer cryptographically-secure.
| Blake3 |
Provides a pure Java implementation of the
Blake3 hash function which can be used for computing
cryptographic hashes
(message digests) which are extensible to arbitrary output lengths (known as an extensible-output
function or XOF), computing
message authentication codes
using a 32 byte (256-bit) secret key, computing subkeys from a primary key using a
key derivation function, and can be
used as the basis for a
cryptographically-secure pseudorandom number generator.
WARNING: Blake3 is not a password hashing algorithm! An algorithm such as Argon2 is more appropriate for password hashing. |
| Crypt | GNU libc crypt(3) compatible hash method. |
| DigestUtils | Simplifies common MessageDigest tasks and provides GNU libc crypt(3) compatible password hashing functions. |
| HmacUtils |
Simplifies common Mac tasks.
Note: Not all JCE implementations support all algorithms. If not supported, an IllegalArgumentException is thrown. |
| Md5Crypt | The libc crypt() "$1$" and Apache "$apr1$" MD5-based hash algorithm. |
| MurmurHash2 | Implementation of the MurmurHash2 32-bit and 64-bit hash functions. |
| MurmurHash3 | Implementation of the MurmurHash3 32-bit and 128-bit hash functions. |
| PureJavaCrc32 | A pure-java implementation of the CRC32 checksum that uses the same polynomial as the built-in native CRC32. |
| PureJavaCrc32C | A pure-java implementation of the CRC32 checksum that uses the CRC32-C polynomial, the same polynomial used by iSCSI and implemented on many Intel chipsets supporting SSE 4.2. |
| Sha2Crypt | SHA2-based Unix crypt implementation. |
| UnixCrypt | Unix crypt(3) algorithm implementation. This class only implements the traditional 56 bit DES based algorithm. |
| XXHash32 | Implementation of the xxHash32 hash algorithm. |
| 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. |
| PercentCodec | Implements the Percent-Encoding scheme, as described in HTTP 1.1 specification. |
| 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.
