The present invention is directed to a system and method for adding data encryption services to a document processing device. Encryption enablement software, which includes two alternate encryption mechanisms, is received by an associated document processing device. The device then awaits an associated user's selection of an electronic document file to be encrypted and subsequently encrypts the file using one of the available encryption mechanisms. The electronic document file is divided into blocks having a preselected length. An encryption key block containing first and second key portions, is then generated. The electronic data file is then encrypted using the first encryption key portion to form first level encryption data. The first level encryption data is then decrypted using the second encryption key portion to form second level encryption data. The second level encryption data is then encrypted using the first key portion to form a final encrypted electronic document file.
