Beginning with Quicken 2003, Intuit protected its Quicken files withvery strong encryption. This protection made it impractical for people to use brute force techniques to discover passwords that would unlock Quicken files.
It appears, however, that Intuit included a backdoor in the product. This backdoor allows Intuit to offer their own affordable service whereby Intuit will unlock a customer's file. To deliver this service, Intuit uses a 512-bit RSA key known only to Intuit. Before Elcomsoft's discovery of Intuit's backdoor, Intuit was the only organization that could unlock their customers' files. We used the advanced decryption technology to uncover Intuit's undocumented and well-hidden backdoor, and to successfully perform a factorization of their 512-bit RSA key. Advanced Intuit Password Recovery 2.0 provides instant removal of Quicken passwords for versions 2003 through 2007, regardless the password length and complexity.
