ECDHE, ECDSA

ECDHE: Elliptic Curve Diffie-Hellman Ephemeral. It's a key exchange algorithm that allows two parties to establish a shared secret over an insecure channel. ECDHE is often used in SSL/TLS protocols to secure data transmission.

ECDSA: Elliptic Curve Digital Signature Algorithm. It's a digital signature algorithm that uses elliptic curve cryptography to provide data integrity and authenticity. ECDSA is widely used for digital signatures in various cryptographic protocols and systems.
