Andrea Paternesi created PDFBOX-3065:
----------------------------------------
Summary: Right now PDFBOX does not permit to sign multiple files
while calling an external signing service.
Key: PDFBOX-3065
URL: https://issues.apache.org/jira/browse/PDFBOX-3065
Project: PDFBox
Issue Type: Improvement
Components: Signing
Affects Versions: 1.8.10
Environment: Any Operating systems.
Reporter: Andrea Paternesi
Fix For: 1.8.11, 2.0.0
Since to sign a PDF you forced the implementation of the SignatureInterface
interface, is not possible to prepare N hashes from N PDF files and then send
them to a signing service that accepts multiple hashes with a single signon.
For example if I use an OTP signing service.
What would be nice to have is to separate the hash calculation from the
signing.
Instead to implement the Interface I would like to have something like this:
1) calculate hash from document with the new signature dictionary bytes
2) sign the hash
3) insert the signature into pdf
This way I could achieve to sign for example 100 pdf files calling the service
once.
Right now must ask the user to sign in 100 times.
Thanks in advance.
Andrea.
