PDFBUNDLE can strengthen file security by adding professional encryption and unique restrictions.
The encryption can be chosen from 6 different algorithms: from the fastest (and longest-running) RC4 algorithm to the military-grade AES-256 revision6 algorithm - with or without passwords.
Passwords can be set as "default" for all files processed or individually when a unique and configurable key can be provided for your company or customer (e.g. LOGIN-NAME, ID-Number, Contract-ID, ...).
Do you only need restrictions? PDFBUNDLE also allows you to set PRINT (or only HIGH QUALITY PRINT) restrictions applicable to each file and also offers a unique EXPIRATION DATE restriction for increased file security.
All password-protected documents can also have a "master password", which removes any restrictions on printing or modifying the file (unless signed by a CERTIFIED signature).
