Class Sha2Crypt

java.lang.Object

com.epam.reportportal.apache.commons.codec.digest.Sha2Crypt

public class Sha2Crypt
extends java.lang.Object

SHA2-based Unix crypt implementation.

Based on the C implementation released into the Public Domain by Ulrich Drepper <drepper@redhat.com> http://www.akkadia.org/drepper/SHA-crypt.txt

Conversion to Kotlin and from there to Java in 2012 by Christian Hammers <ch@lathspell.de> and likewise put into the Public Domain.

This class is immutable and thread-safe.

Since:

1.7

Method Detail

sha256Crypt

public static java.lang.String sha256Crypt(byte[] keyBytes)

Generates a libc crypt() compatible "$5$" hash value with random salt.

See Crypt.crypt(String, String) for details.

Parameters:

keyBytes - plaintext to hash

Returns:

complete hash value

Throws:

java.lang.RuntimeException - when a NoSuchAlgorithmException is caught.

sha256Crypt

public static java.lang.String sha256Crypt(byte[] keyBytes,
                                           java.lang.String salt)

Generates a libc6 crypt() compatible "$5$" hash value.

See Crypt.crypt(String, String) for details.

Parameters:

keyBytes - plaintext to hash

salt - real salt value without prefix or "rounds="

Returns:

complete hash value including salt

Throws:
