PDF Signature Signer

PDF Signature Signer is an application that aims to give authenticity to important PDF files, documents that have been written by an individual who wants to make sure the content is protected against possible intellectual thefts or needs to confirm to an authority the importance of the content itself. Using this program is not difficult, yet it requires some knowledge about digital signatures, certificates, and other similar elements.
PDF Signature Signer works with one specific certificate type, PKCS#12. Various standards bring different levels of certification and security. You'll need to do some research before you know for sure what type of authentication you need. The best part is that you can sign PDF documents in bulk with this tool. This is especially great for productivity levels in different work environments.
An electronic signature requires the user to acquire a digital certificate. In this particular case, you'll need the X.509 PKCS#12 type. Make sure you remember the passkey you've associated with the certificate so that every time you're asked for it you can provide it for easy identification. Keeping in mind that this particular type of security is associated with Personal inFormation eXchange or PFX could also shed some light on the usefulness of the app.
