The US software industry warned this week that the draft regulations published by the US government to allow companies to sell their encryption products internationally were complicated and unrealistic.
In September, Al Gore, the vice president and presidential candidate, made a speech in Silicon Valley that led the industry to believe export restrictions would be removed.
But when the draft regulations were published this week, they were widely seen to fall short of what industry was expecting.
The industry's main bone of contention was that, rather than being removed, the export controls had been superseded by a complicated set of rules and regulations.
Robert Holleyman, president of the Business Software Association, said: "Unfortunately, today's draft falls short of what was promised on 16 September when the Administration said that the new regulations would shift the current process from an antiquated licensing scheme to a realistic reporting scheme."
"Unfortunately, what we see today is a complicated, unrealistic licensing scheme," he added.
His words were mirrored by Ed Gillespie, executive director of Americans for Computer Privacy, an advocacy group consisting of software companies and associations that are concerned about the effect encryption has on individual privacy.
Gillespie said: "The September 16 announcement indicated that all encryption products - including mass market products - would be freely exportable to individuals and commercial firms the world over, with the exception of the seven terrorist nations."
He continued: "The draft regulations make progress, but fall short of the breakthrough announced in September. Instead of a clean lifting of export restrictions, we have a complicated morass of regulations."
Both men said they intended to go back to the White House and push for changes to the draft. Interested parties have until 6 December to submit comments on the proposals, before the Department of Commerce releases its final regulations on 15 December.
A spokesman for the Bureau of Export Administration, which oversees encryption policy, said officials both expected and welcomed feedback and described the draft as a work in progress.
"We felt at this point in the process that the smartest thing to do was to get the paper out and get comment so that we can go back to the drawing board," he said.
The Republican led Congress has wanted to allow software companies to export their strongest encryption products for some time, but the Democratic White House has sided with the likes of the FBI, which claim that such offerings are an asset to terrorists and drug cartels.
