However, in computer technology and especially in the Information Age, this has become trivial to bypass. The technology may be developed or redeveloped in the targeted country in several ways. To begin with, many countries have their own cryptographic research. If a particular nation's technology if of interest, a traveler can purchase a book and return home, or the equivalent web page can be accessed. A necessary result is that the implementation can be done in the country to which the product may not be exported.
Some countries go as far as to ban the use of encryption entirely.
This approach, of course, makes the entire concept of Key Escrow moot, and can only be supported if one starts from the assumption that all information is available to random wiretap. It therefore has all the problems of Key Escrow and Legal Intercept, and no definable controls. It only makes sense in a country which fundamentally views its citizens as untrustworthy, which is an interesting observation given the stated ideals of some of the countries which take this course. But this approach has a bigger problem in the Internet. If encryption is unlawful to use at all, it is unlawful to use to secure the Internet infrastructure, and the insecurity of the Internet is enshrined in law.
