asymmetrical encryption

Asymmetrical encryption uses two related but different keys: a public key and a private key. The public key is shared openly and used to encrypt data, ensuring that only someone with the matching private key can decrypt and read it. Conversely, the private key is kept secret. This system allows secure communication without sharing private keys, making it ideal for protecting sensitive information online, such as during secure email exchange or online transactions. It ensures that data remains confidential and authentic, as only the intended recipient with the private key can access the message.
