Input

{
  "url": "https://en.wikipedia.org/wiki/Public-key_cryptography"
}

Output

{
  "title": "Public-key cryptography",
  "summary": "Public-key (asymmetric) cryptography pairs a freely shared public key with a secret private key. Anyone can encrypt to the public key, but only the holder of the private key can decrypt; conversely, only the private key can produce a signature the public key verifies. The article covers the RSA, Diffie-Hellman, and elliptic-curve families and how they underpin TLS, SSH, PGP, and blockchain wallets.",
  "key_points": [
    "Asymmetric pairing of public + private keys",
    "Enables encryption to a recipient without a shared secret",
    "Enables verifiable signatures",
    "Underlies TLS, SSH, PGP, and crypto wallets",
    "Vulnerable to large-scale quantum attacks against current algorithms"
