After made iText worked on Google App Engine, I built Another application, Remove PDF Password Online. It bases on iText 2.1.7 but with many modification.
the main features of pdfdecrypt online are,
- remove restrictions on any secured PDF document (you should have the right to do it, for example, if you forgot the password). Any Acrobat version up to 9 is supported, even with 128-bit AES or 128-bit RC4 encryption. PDF restrictions removal is an instant process. Unlocked file can be opened in any PDF viewer without any restrictions so you may edit/copy/print it.
- remove the PDF open password. Decryption of the file with password for opening is guaranteed for PDF files Any Acrobat version up to 9 is supported, even with 128-bit AES or 128-bit RC4 encryption,but you must know the password first.
It supports upload PDF documents from your disk and give a PDF url.
If you like it, just have a try now, it is free.
