title: HMAC 256 vs HMAC 512 JWT signature encryption
body: <p>Is there practical difference between HS256 and HS512 encryption algorithms, or is the additional security from longer key redundant compared to already unbreakable key? Which one should I use to encrypt the JWT token?</p>
  
  <p>Is it even possible to use HS512 encryption with auth0's <a href="https://github.com/auth0/java-jwt" rel="noreferrer">java JWT</a>?</p>
