title: Rijndael support in Java
body: <p>We have a requirement to do some Rijndael development in Java.</p>
  
  <p>Any recommendations for articles, libraries etc. that would help us? </p>
  
  <p>Any pointers to keystore maintenance and how store the keys securely?</p>
  
  <p>Edit: </p>
  
  <p>It would need to be open source. Essentially, it's just standard encrypt / decrypt of data using Rijndael. </p>
