In depth
A closer look at PDF Signature Signer
PDF Signature Signer is a handy application that allows you 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. PDF Signature Signer features bulk signing that enables you to sign multiple PDF files by selecting input and output directory, and it doesn't limit the number of PDF files to be signed. PDF Signature Signer helps deploy the digital signing capability across organizations and simplifies the process of signing large numbers of PDF documents with electronic signature to confirm the identity of the originator or reviewer.
