Asymmetric encryption is a method of protecting data that uses two different keys. One key encrypts the data while the other key decrypts it.

The two keys are called a public key and a private key. The public key can be shared with others, but the private key must remain secret.

How It Works

• The sender uses the recipient’s public key to encrypt data.
• The encrypted data travels across the network.
• The recipient uses their private key to decrypt the data.
• Only the matching private key can decrypt data encrypted with the public key.

Common Uses

• Securing websites with HTTPS.
• Protecting email communications.
• Verifying digital signatures.
• Securing VPN connections.
• Safely exchanging encryption keys.
