Decrypt pdf-files in java

843810Aug 11 2004 — edited Aug 17 2004

Hi

Is it possible to decrypt an encrypted pdf-file in java? The file has no password but is encrypted with 40-bit RC4.

The tool I am developing is downloading some pdf-files and tries to merge them. But encrypted pdf-files can not be merged. So I need to decrypt every pdf-file automatically.

Does anyone have experience with automatic decryption of pdf-files?
