  1. Long: curves
  2. Arg: <algorithm list>
  3. Help: (EC) TLS key exchange algorithm(s) to request
  4. Protocols: TLS
  5. Added: 7.73.0
  6. ---
  7. Tells curl to request specific curves to use during SSL session establishment
  8. according to RFC 8422, 5.1. Multiple algorithms can be provided by separating
  9. them with ":" (e.g. "X25519:P-521"). The parameter is available identically
  10. in the "openssl s_client/s_server" utilities.
  11. --curves allows a OpenSSL powered curl to make SSL-connections with exactly
  12. the (EC) curve requested by the client, avoiding intransparent client/server
  13. negotiations.
  14. If this option is set, the default curves list built into openssl will be
  15. ignored.
