Cryptographic key exchange
WebECDH is a method for key exchange and ECDSA is used for digital signatures. ECDH and ECDSA using 256-bit prime modulus secure elliptic curves provide adequate protection for sensitive information. ECDH and ECDSA over 384-bit prime modulus secure elliptic curves are required to protect classified information of higher importance.
