Basic edition of the program, that is only able to remove restrictions (from printing, selecting text and graphics and copying them into the Clipboard, adding/changing annotations and form fields). Does not handle PDF files with "open" password set, if that password is not known.

This edition has all functionality of the Standard one, but also allows to search for "owner" and "user" passwords with brute-force and dictionary attacks, effectively optimized for speed. In addition, it has the "Key search attack", which guarantees the decryption (regardless the password length and complexity) of PDF files that use 40-bit encryption.

Based on Professional edition, this one has an improved "Key search attack" using state-of-the-art "time-memory trade-off" technology, allowing to break "user" password (for 40-bit encryption) in just a few minutes (instead of days, as in Professional edition), using special pre-computed tables.
