Encryption software

Encryption software locks a file or message. Only users with the same encryption software, or the necessary password to open the file, can read files which have been encrypted. So-called “keys,” which are sometimes based on randomly generated numbers, are usually used to open the files. There are many different encryption packages commonly available. Encryption software is embedded in many computer programs, from electronic garage door openers to ATM machines.

Attempts have been made in several countries to make “key escrow” of encryption software mandatory. Under the various key escrow plans, either the makers or the users of encryption software would lodge with governments or designated “third parties” the keys to the software that would allow law officials to read any file.

While supporters of key escrow feel that access to encryption keys is critical in order for law enforcement to be able to do their job properly, many opponents to key escrow fear misuse of the escrow system. Critics of the plan point out the potential for human error or abuse of the system and the technical problems inherent in the plan. China has recently demanded that “keys” to encryption software be lodged with that government.
