Clipper has been accepted as FIPS 185 [NIS94a] by the federal government. There were some suggestions that Clipper might be abandoned when Vice President Gore invited the industry to look into alternative ciphers that implemented key escrow technology. However, both Clipper and Capstone are being produced and sold with extensions planned. Already 9000 units of the Clipper chip has been sold to federal agencies and about 1000 units have been sold to commercial users.
