> ECDSA Support in OpenSSL:
Elliptic Curve Digital Signature Algorithm (ECDSA) is a variant of the Digital Signature Algorithm (DSA) which uses Elliptic Curve Cryptography (ECC). Note that only the nistp256 and nistp384 curves are supported.
> ECDHE Support in OpenSSL: Ephemeral Elliptic Curve Diffie-Hellman (ECDHE) is supported, which allows for Perfect Forward Secrecy with much lower computational requirements.
