FAQs on Document Signing Certificate

QWhat is a Document Signing Certificate?

A Document Signing Certificate is an electronic file issued by a Certificate Authority (CA). It contains a pair of secure digital key for assuring signer’s identity authentication and integrity of electronically transmitted documents.

QHow do digital signatures work?

Digital signatures, like handwritten signatures, are unique to each signer. It uses public key infrastructure (PKI), which is considered the gold standard for digital identity authentication and encryption. PKI relies on the use of two related keys, a public key and a private key, that together create a key pair to encrypt and decrypt a message using strong public key cryptography algorithms. Using both public and private keys that are generated to provide the signer with their own digital identity, a digital signature is generated and encrypted using that signer’s private key, and also a timestamp of when the document was signed using the key. These keys are normally saved in a secure manner; for example, Sectigo and DigiCert sends USB with your certificate and keys to you.

QWhat need to know before you place an order?

Validation is an important part of certificate issuing process. As such, every CA has followed stringent validation policies and procedures to strengthen the security of certificate operations and the validation processes. Take Sectigo for example, and this is the validation materials needed below:

The identity of the Applicant
The identity and address of the entity to confirm its physical existence
That the entity has authorized the issuance of the certificate

The validation work is done by Sectigo. You are required to respond to emails, follow instructions and provide the requested documents.
