parsePkcs12 generating an incorrect private key

[pedroserretti]

Hi!
I'm doing a function to sign my XML's by my .pfx file, so i need to parsePkcs12 to get private key.

I've already tested with one certificate and it does successfully, but when i tested with another certificate, my XML wasn't signing anymore.

So i generated a PEM file from my PFX file to compare. When i analyzed, i realized that my PEM generated from parsePkcs12 was different of my PEM file.

Here's an example of what's coming for me:

Initials from my PEM file:

-----BEGIN PRIVATE KEY-----
MIIEvQIBADAN... (omitted)

... WiCjgGs9A= (omitted)
-----END PRIVATE KEY-----

Initials from PEM generated by parsePkcs12:

-----BEGIN PRIVATE KEY-----
MIIEzAIBADANBgkqh... (omitted)

...8xBAMCABA= (omitted)
-----END PRIVATE KEY-----

Can anyone help me please??
Thanks!
