This sample demonstrates how to place a digital signature into a PDF file generated by
DLI. This signature will be compatible with the Adobe self-sign plugin, and will
contain an x.509 certificate.
NOTE: Included in this project is a file "rsasign.cpp", containing a very slow
implementation of the RSA encryption algorithm. Datalogics does not recommend
using this implementation as a basis for Production code.
DLI can also produce signatures with PCKS #7-format certificates, for the Adobe selfsign
plugin and the VeriSign signature plugin. Customers wishing to do this will
follow a slightly different path, and must be able to generate these certificates.
This sample uses a dummy x.509 certificate; the key pair used to generate this
certificate is stored in the sample.key.info file in the @Data directory.
As of Adobe PDF Library v6.1.1 and DLI v3.0.23, this sample application produces
digital signatures compatible with the Adobe Acrobat v5 validation plug-in. In a
future release, DLI will be upgraded to generate digital signatures compatible with
