PDF Crack Security is a program to recover passwords for Adobe Acrobat PDF files.

PDF Crack Security can be used to decrypt protected Adobe Acrobat PDF files, which have "owner" password set, preventing the file from editing (changing), printing, selecting text and graphics (and copying them into the Clipboard), or adding/changing annotations and form fields. Decryption is being done instantly. Decrypted file can be opened in any PDF viewer (e.g. Adobe Acrobat Reader) without any restrictions -- i.e. with edit/copy/print functions enabled. All versions of Adobe Acrobat (including 5.x, which features 128-bit encryption) are supported.

PDF Crack Security is used by simply dragging one or more files, or even an entire folder, onto the PDF Crack Security product. You can even use it in shell scripts or with Automaton scripts.

PDF Crack Security is not compatible with DRM'ed eBooks from eStores (protected by FileOpen, etc.). PDF Crack Security is designed to help you work with PDF files when you've lost your password, or when you need to process your PDF files all at once.

The reference information:

A PDF document can be encrypted (PDF 1.1) to protect its contents from unauthorized access. Encryption applies to all strings and streams in the document’s PDF file, but not to other object types such as integers and boolean values, which are used primarily to convey information about the document’s structure rather than its content. Leaving these values unencrypted allows random access to the objects within a document, whereas encrypting the strings and streams protects the document’s substantive contents.

Note: When a PDF stream object (see Section 3.2.7, “Stream Objects”) refers to an external file, the stream’s contents are not encrypted, since they are not part of the PDF file itself. However, if the contents of the stream are embedded within the PDF file (see Section 3.10.3, “Embedded File Streams”), they are encrypted like any other stream in the file. Beginning with PDF 1.5, embedded files may be encrypted in an otherwise unencrypted document (see Section 3.5.4, “Crypt Filters”).

Encryption-related information is stored in a document’s encryption dictionary, which is the value of the Encrypt entry in the document’s trailer dictionary (see Table 3.13 on page 97). The absence of this entry from the trailer dictionary means that the document is not encrypted. The entries shown in Table 3.18 are common to all encryption dictionaries.

The encryption dictionary’s Filter entry identifies the file’s security handler, a software module that implements various aspects of the encryption process and controls access to the contents of the encrypted document. PDF specifies a standard password-based security handler that all consumer applications are expected to support, but applications may optionally provide security handlers of their own.
