What is the most popular encryption SHA using Java language
public static SecretKey getKeyFromPassword(String password, String salt)
throws NoSuchAlgorithmException, InvalidKeySpecException
{ SecretKeyFactory factory = SecretKeyFactory.getInstance("PBKDF2WithHmacSHA256");
KeySpec spec = new PBEKeySpec(password.toCharArray(), salt.getBytes(), 65536, 256);
SecretKey secret = new SecretKeySpec(factory.generateSecret(spec) .getEncoded(), "AES");
return secret;
}
The symmetric-key block cipher plays an important role in data encryption. It means that the same key is used for both encryption and decryption. The Advanced Encryption Standard (AES) is a widely used symmetric-key encryption algorithm.
In this tutorial, we’ll learn how to implement AES encryption and decryption using the Java Cryptography Architecture (JCA) within the JDK.
