Signing a PDF document with a Digital Signature Certificate (DSC) is a secure way to authenticate the identity of the signer and ensure the integrity of the document. The use of DSCs for signing PDF documents is not just about applying a cryptographic signature; it’s about building trust in digital transactions. When you sign a PDF with a DSC, you provide assurance to the recipient that the document has not been altered in transit, and that it truly comes from you, thus preserving the non-repudiation aspect of digital communications.

Introduction to Digital Signature Certificate
A Digital Signature Certificate is an electronic format of a certificate that proves your identity electronically. It also provides you with a high level of security for online transactions by ensuring absolute privacy of the information exchanged using a digital certificate. Digital signatures use public key infrastructure (PKI) for the highest level of security.
Digital signatures are not merely electronic signatures; they are unique identifiers akin to a fingerprint. When you sign a document with a DSC, you are embedding encrypted information that is exclusively associated with you. This process is facilitated by public key infrastructure (PKI), which uses two keys: a public key, which is available to everyone, and a private key, which remains confidential to the owner of the DSC.
Why Use a Digital Signature Certificate?
- Authentication: Confirms the identity of the signer.
- Integrity: Ensures that the document has not been altered.
- Non-repudiation: Prevents the signer from denying the authenticity of their signature.
Moreover, in many legal contexts, a DSC carries the same weight as a handwritten signature, making it a critical tool for businesses and individuals alike. It streamlines processes, saves time, and reduces the carbon footprint associated with printing and shipping documents.
