Technology Removes 40-Bit Adobe PDF Encryption
<strong>Moscow — Oct. 18</strong><br />ElcomSoft Co. Ltd. has released version 4.0 of the Enterprise version of its Advanced PDF Password Recovery software. <br /><br />This program makes it easy to remove both password encryption and usage restrictions from Adobe Acrobat PDF files. APDFPR Enterprise supports all Adobe Acrobat versions (up to 8.0), including those that use AES encryption, and guaranteed recovery of PDF files with 40-bit encryption using state-of-the-art “time-memory trade-off” techniques.<br /><br />ElcomSoft has introduced technology that ensures all 40-bit encryption keys can be unlocked in minutes. <br /><br />Using the old-fashioned “brute force” technique, PDF files could be opened in four to five days. <br /><br />Earlier this year, ElcomSoft introduced a “rainbow attack” subsystem, which unlocked an estimated 99.9 percent of locked PDF files. <br /><br />Version 4 of Advanced PDF Password Recovery software, with its new “thunder tables” technology (patent pending), raises the success rate from 99.9 to 100 percent of locked PDF files.
