> As long as the government can keep a private key secure... Which government? Software crosses borders. You can bet that if the US mandated a back door to be inserted into software that was being exported to another country, that country would want to either have the master key for that back door, or a different version of the software with a different back door or without the back door. A software user could choose the version of the software that they wanted to use according to which country (if any) could snoop on them. It's unworkable.
