Signing with p12 certificate with password

[Arturokin]

Hello,
Reading the docs i can't find an example of how to sign un p12 certificate, i tried using one in base64 but nothing happens,

Mi question is, pkcs7 format requires public and private files to be separated, to sign the PDF, i can convert the p12 to pkcs7 dividing the two types (public and private), but when calling signPdf function, what do i use? private or public certificate? can you help me out on this?

I also would love to know if it's possible to use p12 certificates with this library.
