WebECDH - Elliptic Curve Diffie–Hellman. ECDH is a protocol that allows two parties to establish a shared secret over an insecure channel. Each party has a public-private key pair. The public key is sent from each party to the other one. The private key must be kept secret. A shared secret is data that is known only to the involved parties. 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. Hash truly meals https://connectedcompliancecorp.com
