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. See http://publib.boulder.ibm.com/httpserv/manual70/mod/mod_ibm_ssl. html for full details. This fix is targeted for IBM HTTP Server fix packs: - 8.0.0.6 - 8.5.0.2
