title: RSA Encryption using PL/SQL or Cobol
body: <p>I would like to encrypt a String before sending it over to my client.
  The client has given me a RSA Public Key.
  There is a 512 bytes of Modulus and 6 bytes of Pub. Exp. (all Hex).</p>
  
  <p>Normally I am running Cobol to produce this output file. But I dont think Cobol has any api/call to encrypt.
  So I was planning of calling an Oracle procedure/function to do this.</p>
  
  <p><strong>Question:</strong> How can I encrypt a string using RSA public key in Oracle PL/SQL (or SQL)?</p>
