Validation checks a signed document and reports who signed it, whether the certificate was trusted, and whether anything changed after signing. It is the step people skip and then regret when a document turns out to have been altered.
Usually that the document changed after signing, or that the certificate had expired or was not from a trusted authority. The report distinguishes these.
Yes. Valid means the maths checks out. Whether you trust the signer's identity is a separate judgement.
No. Only changing and saving the file does.
These tools handle one document at a time. When the job is thousands of files, Greenbooks handles document digitization as a managed service, including bulk scanning, OCR and metadata capture, with the output loaded into DocuVenta DMS. Talk to us about volume work.
