Local fix

Problem summary

• ****************************************************************
  * USERS AFFECTED:  Users of IBM HTTP Server who want to use    *
  *                  Elliptic Curve Cryptography (ECC) ciphers   *
  *                  for                                         *
  *                  SSL.                                        *
  ****************************************************************
  * PROBLEM DESCRIPTION: IHS only supports ciphers that use RSA  *
  *                      key establishment and RSA signatures.   *
  ****************************************************************
  * RECOMMENDATION:  Apply the fix if your environment requires  *
  *                  Elliptic Curve Cryptography (ECC).          *
  ****************************************************************
  Ciphers using ECC key agreement and/or ECC signatures are
  possible in TLSv1.2 but not supported by IBM HTTP Server. See
  RFC 5246 for a full description of TLS1.2 ciphers, added
  ciphers are of the type ECDHE_ECDSA and ECDHE_RSA in terms of
  the RFC.
  

Problem conclusion

• Support for ECDHE-ECDSA and ECDHE-RSA ciphers have been added
  to IHS. ECDHE-RSA ciphers can be used without changing
  certificates, but ECDHE-ECDSA  require special certificates
  with an ECC key.

  This fix is targeted for IBM HTTP Server fix packs:
   - 8.0.0.6
   - 8.5.0.2
