@Lee D - Cryptography has been an arms race between the strength the of the encryption and means to break them. Combined with various mistakes and hardware limitations your observation that the current encryption methods will be obsolete in the a few years is spot on.
Also, people need to remember that encryption does not need to protect information forever but for a period long enough for it to become essentially useless. This is time period that can range from a few minutes or hours to a few years.
