Asymmetric Key Cryptography

Asymmetric key cryptography is a secure method of encrypting data using a pair of keys: a public key and a private key. The public key can be shared openly and is used to encrypt messages. Only the person holding the private key, which is kept secret, can decrypt these messages. This system ensures that even if someone intercepts the encrypted message, they cannot read it without the private key. This technology underpins secure online communications, allowing for secure transactions and privacy without the need to share secret keys beforehand.
