/* 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! ****
