Package org.apache.commons.codec.digest

Simplifies common MessageDigest tasks and includes a libc crypt(3) compatible crypt method that supports DES, MD5, SHA-256 and SHA-512 based algorithms as well as the Apache specific "$apr1$" variant.

Class Summary

Class	Description
Blake3	Implements the Blake3 algorithm providing a hash function with extensible output (XOF), a keyed hash function (MAC, PRF), and a key derivation function (KDF).
Crypt	GNU libc crypt(3) compatible hash method.
DigestUtils	Operations to simplify common MessageDigest tasks.
HmacUtils	Simplifies common Mac tasks.
Md5Crypt	The libc crypt() "$1$" and Apache "$apr1$" MD5-based hash algorithm.
MessageDigestAlgorithms	Standard MessageDigest algorithm names from the Java Cryptography Architecture Standard Algorithm Name Documentation.
MurmurHash2	Implementation of the MurmurHash2 32-bit and 64-bit hash functions.
MurmurHash3	Implementation of the MurmurHash3 32-bit and 128-bit hash functions.
MurmurHash3.IncrementalHash32	Deprecated. Use IncrementalHash32x86.
MurmurHash3.IncrementalHash32x86	Generates 32-bit hash from input bytes.
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.
XXHash32	Implementation of the xxHash32 hash algorithm.
