A **Document Signer Certificate (.pfx)** is a digital certificate used to securely sign electronic documents, ensuring their authenticity and integrity. The `.pfx` file format contains both the private key and the public certificate, allowing users to create digital signatures that verify the identity of the signer and confirm that the document has not been altered. Commonly used in PDF and Word file signing, it is essential for legal, financial, and business processes where document authenticity is critical.
A **Document Signer (HSM)** uses a **Hardware Security Module** to securely generate and store cryptographic keys for digitally signing documents. This hardware-based solution ensures high levels of security, as the private key never leaves the HSM device. It is ideal for organizations that require automated, large-scale, and tamper- proof digital signing processes, offering greater protection than software-based methods like .pfx certificates.
.A Class 2 Document Signer refers to an individual or entity using a Class 2 digital certificate for signing electronic documents.

A Class 3 Document Signer refers to an individual or entity that uses a Class 3 digital certificate to sign electronic documents. This type of digital certificate is issued by a Certificate Authority (CA) after undergoing the highest level of verification and is used for high-security transactions, ensuring both the authenticity of the signer and the integrity of the signed document.
