Since the actual encryption keys are unwieldy binary sequences, they are derived from more user- friendly passwords which consist of plain characters.
In the course of PDF and Acrobat development the PDF encryption methods have been enhanced to use stronger algorithms, longer encryption keys, and more sophisticated passwords. Encryption algorithms, key length, and password length in PDF versions. PDF and Acrobat versionencryption algorithm and key lengthmax. The length of the encryption key used for actually encrypting the document is independent from the length of the password (see table above). PDF encryption internally works with encryption keys of 4. PDF version. The binary encryption key is derived from a password provided by the user.
The password is subject to length and encoding constraints. Up to PDF 1. 7 (ISO 3. Latin- 1 encoding. PDF 1. 7 Adobe Extension Level 3 introduced Unicode characters and bumped the maximum length to 1. UTF- 8 representation of the password. Since UTF- 8 encodes characters with a variable length of 1- 4 bytes the allowed number of Unicode characters in the password is less than 1. ASCII characters.
For example, since Japanese characters usually require 3 bytes in UTF- 8 representation, up to 4. Japanese characters can be used in passwords. In order to avoid ambiguities, Unicode passwords are normalized by a process called SASLprep (specified in RFC 4. Stringprep in RFC 3. This process eliminates non- text characters and normalizes certain character classes (e.
The password is normalized to Unicode normalization form NFKC, and special bidirectional processing is applied to avoid ambiguities which may otherwise arise if right- to- left and left- to- right characters are mixed in a password. It is widely known that names, plain words, etc. Surveys have shown that a significant number of passwords are chosen to be the spouse’s or pet’s name, the user’s birthday, the children’s nickname etc., and can therefore easily be guessed.
