Asymmetric Encryption (Public Key)

Category: science

A cryptographic system utilizing paired keys: a public key for encryption and a private key for decryption.

Asymmetric systems (like RSA or Elliptic Curve cryptography) solve the key-sharing trap. You publish your public key openly so anyone can encrypt a message to you, but only your securely isolated private key possesses the mathematical capacity to reverse the cipher text.

Common Examples

• We deployed asymmetric encryption to secure the API key distribution channel, passing secret tokens across public interfaces safely.
• Asymmetric encryption requires higher processing overhead than symmetric blocks, which is why it is used mostly for handshake stages.
