SignDoc SDK

This topic describes changes in the SignDoc SDK behavior since the previous release.

Certificate chain

After successful verification of the certificate chains, the complete certification chain is returned in the correct order by following functions:

  • de.softpro.doc.SignDocVerificationResult.getCertificates()
  • de.softpro.doc.SignDocVerificationResult.getTimeStampCertificates()

Impact of non-increasing time channel

If the time channel is present and becomes non-increasing, a failure occurs for the following function:

  • de.softpro.doc.SignDocSignatureData.addSample()

Handling of indexed 4-BPP images

Instead of rejecting indexed 4-BPP (bits per pixel) images, they are converted to 8-BPP images by de.softpro.doc.SignDocImage.
