Because not all encryption systems have built-in key recovery mechanisms, there is also a market for recovering keys (and ultimately the plaintext) by other means, for example, brute-force attacks against short keys or attacks that exploit weaknesses in design or implementation. Many systems contain flaws, for example, in key management, that allow them to be cracked despite using long keys. In some cases, the key may be stored on a disk encrypted with a password that can be cracked. AccessData Corp., a company in Orem, Utah, provides software and services to help law enforcement agencies and companies recover data that has been locked out by encryption. In an interview with the Computer Security Institute, Eric Thompson, founder of AccessData, reported that they had a recovery rate of about 80-85% with large-scale commercial commodity software applications [23]. Thompson also noted that former CIA spy Aldrich Ames had used off-the-shelf software that could be broken.
Several governments are adopting encryption policies that favor key recovery systems. The Clinton Administration's policy is to leave the U.S. domestic market unregulated and to ease export controls on products with acceptable key recovery systems. So far, three companies have obtained licenses to export strong encryption with key recovery under regulations established at the end of 1996. Because key recovery provides much stronger protection than short keys, which can be broken by anyone, while also being valuable to customers, other vendors are expected to follow suit and put key recovery capabilities into the export versions of products rather than using short keys. To reduce product development, maintenance, and management costs, vendors may produce a single product line, based on key recovery, for both domestic and international use. However, some companies are ignoring the international market entirely. The Administration's policy has been challenged both by Congressional bills that would lift export controls for products with or without key recovery and by lawsuits claiming that export controls on encryption software are unconstitutional.

The use of encryption is expected to rise rapidly, reaching 60% of U.S. business users by the year 2000. Because organizations have a need to recover the keys to stored encrypted data, including files and saved electronic mail, the use of key recovery with stored data could become standard business practice. Companies will either operate their own key recovery services or use trusted third parties. Self escrow will be allowed with export versions of products sold to approved organizations. Pilot projects in the U.S. and elsewhere are testing different approaches to key recovery.
