Method Detail
sha256Crypt
public static 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:
RuntimeException- when aNoSuchAlgorithmExceptionis caught.
sha256Crypt
public static String sha256Crypt(byte[] keyBytes, String salt)
Generates a libc6 crypt() compatible "$5$" hash value.See
Crypt.crypt(String, String)for details.- Parameters:
keyBytes- plaintext to hashsalt- real salt value without prefix or "rounds="- Returns:
- complete hash value including salt
- Throws:
IllegalArgumentException- if the salt does not match the allowed patternRuntimeException- when aNoSuchAlgorithmExceptionis caught.
sha512Crypt
public static String sha512Crypt(byte[] keyBytes)
Generates a libc crypt() compatible "$6$" hash value with random salt.See
Crypt.crypt(String, String)for details.- Parameters:
keyBytes- plaintext to hash- Returns:
- complete hash value
- Throws:
RuntimeException- when aNoSuchAlgorithmExceptionis caught.
sha512Crypt
