How to hash a password with SHA-512 in Java?

you can use this for SHA-512 (Not a good choice for password hashing). import java.nio.charset.StandardCharsets; import java.security.MessageDigest; import java.security.NoSuchAlgorithmException; public String get_SHA_512_SecurePassword(String passwordToHash, String salt){ String generatedPassword = null; try { MessageDigest md = MessageDigest.getInstance(“SHA-512”); md.update(salt.getBytes(StandardCharsets.UTF_8)); byte[] bytes = md.digest(passwordToHash.getBytes(StandardCharsets.UTF_8)); StringBuilder sb = new StringBuilder(); for(int i=0; i< bytes.length ;i++){ sb.append(Integer.toString((bytes[i] & 0xff) + 0x100, … Read more

Best practice for hashing passwords – SHA256 or SHA512?

Switching to SHA512 will hardly make your website more secure. You should not write your own password hashing function. Instead, use an existing implementation. SHA256 and SHA512 are message digests, they were never meant to be password-hashing (or key-derivation) functions. (Although a message digest could be used a building block for a KDF, such as … Read more
