Do you support Elliptic Curve Diffie-Hellman?

Yes, we do. Although ZRTP always supports classic Diffie-Hellman, Silent Phone also supports the ECDH protocol as defined by NIST SP 800-56A and NSA Suite B, which uses the same elliptic curves as used by ECDSA in FIPS 186-4, Elliptic curve algorithms are the next generation of public key cryptography, offering a level of security that better matches the full key strength of AES-256.
