@cindex SSL Public Key Pin
@item --pinnedpubkey=file/hashes
Tells wget to use the specified public key file (or hashes) to verify the peer.
This can be a path to a file which contains a single public key in PEM or DER
format, or any number of base64 encoded sha256 hashes preceded by ``sha256//''
and separated by ``;''
When negotiating a TLS or SSL connection, the server sends a certificate
indicating its identity. A public key is extracted from this certificate and if
it does not exactly match the public key(s) provided to this option, wget will
abort the connection before sending or receiving any data.
