From the developer:
PDF Signature Signer is a software program to sign PDF documents using X.509 certificates. The supported signing identity is PKCS#12, which evolved from the PFX (Personal inFormation eXchange) standard and is used to exchange public and private objects in a single file. PKCS#12 usually stores a private key with the appropriate public key certificate. PKCS#12 is the only accepted X.509 certificate by PDF Signature Signer.
