Add support for Elliptic curve Diffie-Hellman (ECDH) Cryptography

ECDHE is becoming more common with the systems that connect with z/TPF. We would like to see z/TPF support the newer ciphers before it becomes a security requirement.

    IBM believes this will be satisfied when OpenSSL TLS 1.3 support is provided.

    1. Are you envisioning this being used as part of openSSL?
    Yes, we would be using this with OpenSSL
    2. There is currently no support in the z/TPF keystore to generate ECC keys and certificates - is having the keys / certs in the keystore a requirement?
    No, there is no requirement to generate keys/certs or have them in the keystore.
    3. Is there a timeframe when you would expect ECC to become a security requirement? Or is this just a proactive RFE?
    This is a proactive RFE. The question whether TPF supports this was raised, but there is no specific request yet to do so.

    Currently the supported hardware accelerators (CPACF and CryptoExpress accelerator) do not support ECC ciphers in hardware. So this may be a software only solution initially. Couple of questions:

    1. Are you envisioning this being used as part of openSSL?
    2. There is currently no support in the z/TPF keystore to generate ECC keys and certificates - is having the keys / certs in the keystore a requirement?
    3. Is there a timeframe when you would expect ECC to become a security requirement? Or is this just a proactive RFE?
