It is designed as a cost-effective, high-capacity solution for pressure ratings up to ASME 600 class.

What might a "Multikey 1811" device have looked like? Given the era’s mechanical limitations, it would likely have been a box of wooden gears, brass discs, and sliding bars. Inspired by Alberti’s cipher disk (1467) or Jefferson’s wheel cipher (1795), a multikey device could have featured several concentric rings or multiple stacked disks, each representing a distinct keyed alphabet. To encrypt a message, the operator would first set a primary key (e.g., a date or a word) to determine which disk to use for the first letter. Then, after a certain number of characters, a secondary key—perhaps derived from a different shared secret or a physical switch on the device—would rotate a different set of disks. This created a cipher where the relationship between plaintext and ciphertext changed unpredictably based on multiple variables. In essence, it was a primitive form of multi-factor encryption: something you know (the primary key) and something you configure (the secondary key sequence). multikey 1811

While the Multikey 1811 is robust, it is not immune to implementation errors. Security auditors frequently identify the following issues: Inspired by Alberti’s cipher disk (1467) or Jefferson’s
