cz.d1x.dxcrypto.hash.HashingAlgorithms

public class HashingAlgorithms
extends Object

Factory that provides builders for available hashing algorithms. Create a new builder and when you are done with parameters, call HashingAlgorithmBuilder.build() to retrieve immutable HashingAlgorithm instance.

Method Detail

md5

public static HashingAlgorithmBuilder md5()

Creates a new builder for MD5 hashing algorithm.

More than 10 years, it is NOT recommended to use this algorithm. If you can choose, go with some stronger function (e.g. SHA-256 or SHA-512).

Returns:

builder for MD5

sha1

public static HashingAlgorithmBuilder sha1()

Creates a new builder for SHA-1 hashing algorithm.

This algorithm is stronger than MD5 but it has also its weaknesses. If you can choose, go with some stronger function (e.g. SHA-256 or SHA-512).

Returns:

builder for SHA-1

sha256

public static HashingAlgorithmBuilder sha256()

Creates a new builder for SHA-256 hashing algorithm.

This algorithm should be sufficient for many cases (e.g. password hashing). If slightly higher execution time is not an issue for you, you can also use stronger SHA-512.

Returns:

builder for SHA-256

sha512

public static HashingAlgorithmBuilder sha512()

Creates a new builder for SHA-512 hashing algorithm.

This algorithm should be sufficient for many cases (e.g. password hashing). If you need slightly lower execution time, you can also use SHA-256.

Returns:

builder for SHA-512
