SSL/X.509 and that whole ecosystem can use ECDSA based certificates and ECDH as key exchange, because it is explicitly designed to allow multiple variants of encryption algorithms. There are relatively many widely deployed systems that use ECC because of resource constrains (short signatures, mainly). For example both Microsoft's product keys and FlexLM use something that is at least described in marketing materials as ECDSA. |
