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.

Interface Summary

Interface	Description
GitIdentifiers.TreeIdBuilder.BlobIdSupplier	Supplies a blob identifier that may throw IOException.

Class Summary

Class	Description
B64	Base64-like method to convert binary bytes into ASCII chars.
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).
Blake3.ChunkState
Blake3.EngineState
Blake3.Output	Represents the state just prior to either producing an eight word chaining value or any number of output bytes when the ROOT flag is set.
Crc16	CRC-16 checksum implementations you can customize with a table and init value.
Crc16.Builder	Builds Crc16 instances.
Crypt	GNU libc crypt(3) compatible hash method.
DigestUtils	Operations to simplify common MessageDigest tasks.
GitIdentifiers	Computes Git object identifiers and their generalizations described by the SWHID specification.
GitIdentifiers.DirectoryEntry	Represents a single entry in a Git tree object.
GitIdentifiers.TreeIdBuilder	Builds a Git tree identifier for a virtual directory structure, such as the contents of an archive.
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.
MurmurHash	Commons implementation methods for MurmurHash* classes in this package.
MurmurHash2	Implements the MurmurHash2 32-bit and 64-bit hash functions.
MurmurHash3	Implements 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	Implements the xxHash32 hash algorithm.

Enum Summary

Enum	Description
