Security settings are important for protecting the PDF document’s sensitive information. If you encrypt and secure PDF files to prevent unauthorized access/restrict sensitive operations, you can choose what others can and can't do with your PDF documents including document viewing, printing, editing, and copying which all can be individually turned on or off, offering you a great deal of control in protecting sensitive information.

Black Ice PDF and ColorPlus Printer Drivers PDF Security features will allow:

  • Secure PDF documents using 40-bit or 128-bit RC4 encryption.
  • Restrict unauthorized users from viewing, printing, editing, and copying content from your PDF files.
  • Password-protect PDF files, requiring users to enter a password to open or edit the file.

PDF Security settings can be configured under the Security tab of the PDF Settings dialog.

  • Encryption length: This value defines the length of the encryption key. Available values: No Encryption, 40 bit Encryption, or 128 bit Encryption. Black Ice Printer Drivers use RC4 algorithm for encryption.
  • Password required to open the document (User level): If specified, the document can only be opened with the password. If Owner level password is also set then this password acts as a User password allowing only limited access specified by the Owner. You can specify a user password only if the encryption has been set. If the user password is empty but encryption is turned on, the PDF document will still be encrypted but will not require a password to open the document. Password should be maximum 32 characters.
  • Password required to edit the document (Owner level): If specified, Opening the document with the correct owner password allows complete access to the document. You can specify a Owner password only if the encryption has been set. If the owner password is empty the PDF document will still be encrypted and the user will have all access to the document. Password should be maximum 32 characters.
