C/C++ developer to fix current version of PoDoFo for multiple PAdES signatures
Budget: €36 – €0 EUR
The current version of PoDoFo 0.9.8 (https://github.com/podofo/podofo)
has several issues. The big one is related to incremental updates so that
when we add a second digital signature to a file that already has a digital signature, that first digital signature is invalidated, i.e. acrobat reader says that the signature is not valid because the file has been
modified after the signature.
Also, there are some other issues with some types of non standard pdf structure (for example pdf with forms created by PDF Architect.
The task should be working on podofo to fix all this issues so that we can use it in our apps for iOS.
We also, need someone that can take charge of this task and help us in the future in maintaining our custom version.
