Digital signatures offer a trusted and compliant method to verify the authenticity of electronic records . In contrast to handwritten scans , they employ public-key infrastructure to establish the signer’s verifiable credentials and lock content from post-signing tampering. This renders them essential for contracts, legal agreements, and official paperwork where regulatory compliance demands absolute assurance.

In the era of distributed teams , digital signatures reduce delays while enforcing end-to-end document security.

Before signing in WPS Office , you'll need a trusted electronic credential sourced from a recognized CA . Common examples include credentials from DigiCert, GlobalSign, or Sectigo , link your legal identity to encrypted signing credentials. Corporations often issue them through centralized IT infrastructure , while private users can acquire them through certified vendors . If no certificate is present, WPS cannot generate a cryptographically valid signature .

Once you have your certificate , open the document in WPS’s document module. Navigate to the Review tab on the ribbon , then activate the digital signature function . A prompt for signing parameters displays, where you can pick the correct key from your store and position the visual seal . After clicking Apply, WPS will lock the document with a certified digital fingerprint , which manifests as an embedded stamp or signature box . This ensures document immutability , blocking all modifications after certification .

End users opening the certified document can easily verify its authenticity using WPS Office . All they need to do is launch the document , go to the Verification menu , and click Verify . The software will check the certificate's validity and confirm whether the document remains unaltered . This step delivers real-time validation , that the signature remains valid and the content unmodified.

Integrating digital signatures into your workflow with WPS Office accelerates approvals, minimizes environmental impact, and fortifies confidentiality . Whether you're finalizing contracts from home , this feature upholds their enforceability across jurisdictions . Implementing e-signatures in WPS is a straightforward leap forward toward next-generation digital governance .
