(PHP ActiveX) Load Certificate from PFX (PKCS#12)

Loads a digital certificate (and private key, if available) from a PFX file.(also known as PKCS#12)

Note: This example requires Chilkat v11.0.0 or greater.

Chilkat ActiveX Downloads ActiveX for 32-bit and 64-bit Windows Note: The php_com_dotnet.dll may need to be enabled inside of php.ini.

// A PFX typically contains certificates in the chain of authentication.
// The Chilkat cert object will choose the certificate w/
// private key farthest from the root authority cert.
// To access all the certificates in a PFX, use the 
// Chilkat certificate store object instead.

// then get the private key...

// The private key object may be used in any Chilkat methods
// (in other objects/classes) that expect a private key argument.

// In this case, save the private key to a PKCS8 Encrypted PEM format file:
