-/* some requirements for this to work:
- 1. set pCertFile to the file with the client certificate
- 2. if the key is passphrase protected, set pPassphrase to the
- passphrase you use
- 3. if you are using a crypto engine:
- 3.1. set a #define USE_ENGINE
- 3.2. set pEngine to the name of the crypto engine you use
- 3.3. set pKeyName to the key identifier you want to use
- 4. if you don't use a crypto engine:
- 4.1. set pKeyName to the file name of your client key
- 4.2. if the format of the key file is DER, set pKeyType to "DER"
-
- !! verify of the server certificate is not implemented here !!
-
- **** This example only works with libcurl 7.9.3 and later! ****
