title: Difference Between RSA-OAEP and RSA-PKCS1.5
body: <p>What is the different between RSA-OAEP and RSA-PKCS1.5?
  My understanding is they are both RSA encryption, but using different padding schemes.
  What is the advantage of one over the other?
  If I generate a RSA 2048 pirate and public key pair, can I use the same key pair to encrypt and decrypt a message that is OAEP padded vs PKCS1.5 padded?</p>
