The ECDHE is used for establishing the keys for that, using the SHA-256 for deriving the message encryption keys. The ECDSA is used for entity authentication. Everything but AES-GCM is in the handshake, so they are relatively inconsequential unless you've got very little data to encrypt. Anyway, the ECDH / ECDSA with 256 bit keys is also about as fast as you may wish. | |

@MaartenBodewes is that any different to what i'm currently using ECDHE-ECDSA-AES128-GCM-SHA256? (feel free to treat me as clueless, this isn't my area of expertise)
