positive.code: === ECDSA vs EdDSA ?
  
  ECDSA algorithm has one very weak point - it requires cryptographically secure
  random numbers not  for key generation but also for EVERY signature creation.
  
  If attacker has two signatures for same data and can guess random number used
  for their creation, then she can calculate private key (see PS3 ECDSA exploit
  
negative.code: 
  Currently supported JWK key types are
  
  * RSA key pairs (No RSA-CRT support yet)
  * OKP key pairs (Ed25519)
  * EC key pairs (P-256, P-384, P-521 curves)
