The correct answer is Public Key Infrastructure (PKI) certificates. PKI certificates are essential for securing documents as they provide a framework for the creation, management, and distribution of digital certificates. These certificates help in encryption, decryption, and authentication processes, ensuring that only authorized users can access or modify sensitive information.

PKI relies on a combination of hardware, software, policies, and standards to support secure communications and information exchange. By using PKI certificates, organizations can ensure the integrity, confidentiality, and authenticity of documents and data, making them a critical component for security protocols.

The other options do not encompass the full range of functionalities provided by PKI. Digital signatures, while related to PKI, do not consist of a framework for managing certificates; they are rather a specific use of asymmetric cryptography that ensures data integrity and verifies the identity of the sender. SSL (Secure Socket Layer) certificates are part of secure internet communications but are essentially a specific implementation within the broader PKI paradigm. Therefore, while both SSL and Digital Signatures rely on PKI, they do not represent the full spectrum of capabilities that PKI certificates offer for securing documents.
