--pubkey

Public key filename. Allows you to provide your public key in this separate file.

curl attempts to automatically extract the public key from the private key file, so passing this option is generally not required. Note that this public key extraction requires libcurl to be linked against a copy of libssh2 1.2.8 or higher that is itself linked against OpenSSL. (Added in 7.39.0.)
