title: AES Encryption/decryption using Spring Security
body: <p>I've been looking all over the internet on how to encrypt/decrypt a password or a String using AES in Spring Framework. Any links or tutorials? Explaining AES is good too but please use a non-nerd words. </p>
  
  <p>If you're wondering why should I do this is because we need to encrypt the password and save it in the session and get it from the session to decrypt then use it.</p>
  
  <p>Thanks in advance.</p>
