Asymmetric EncryptionUses a pair of keys: a public key and a private key. The public key can be freely distributed, while the private key must be kept secret. This tool provides two main applications of asymmetric encryption.

• RSA-OAEP:is a secure asymmetric encryption scheme, often used to encrypt small amounts of data (like a session key). You encrypt with the recipient's public key, and the recipient decrypts with their own private key.
• ECDH (Elliptic-curve Diffie-Hellman (ECDH)): A key exchange protocol. It allows two parties, with no prior shared secret, to establish a shared secret key over an insecure channel by exchanging some information (their public keys). This shared secret can then be used for symmetric encryption (e.g., AES).
