1 Long: pinnedpubkey 2 Arg: <hashes> 3 Help: FILE/HASHES Public key to verify peer against 4 Protocols: TLS 5 --- 6 Tells curl to use the specified public key file (or hashes) to verify the 7 peer. This can be a path to a file which contains a single public key in PEM 8 or DER format, or any number of base64 encoded sha256 hashes preceded by 9 \'sha256//\' and separated by \';\' 10 11 When negotiating a TLS or SSL connection, the server sends a certificate 12 indicating its identity. A public key is extracted from this certificate and 13 if it does not exactly match the public key provided to this option, curl will 14 abort the connection before sending or receiving any data. 15 16 PEM/DER support: 17 7.39.0: OpenSSL, GnuTLS and GSKit 18 7.43.0: NSS and wolfSSL/CyaSSL 19 7.47.0: mbedtls 20 7.49.0: PolarSSL 21 sha256 support: 22 7.44.0: OpenSSL, GnuTLS, NSS and wolfSSL/CyaSSL. 23 7.47.0: mbedtls 24 7.49.0: PolarSSL 25 Other SSL backends not supported. 26 27 If this option is used several times, the last one will be used. 28
