One good candidate would be Enigma 2000, now available as Enigma 2000 Plus:

http://www.drchip.de/html/enigma_2000_plus.html

Unfortunately, there is little information available, but from what I 
saw a few years ago, this is a polyalphabetic cipher with a large key.

 From the web site: "Die Kombination aus der Vernam-Codierung 
(One-Time-Pad) und des von T. Heidel zum Patent angemeldeten Verfahrens 
macht eine "bis zu beweisbar sichere Dateiverschlüsselung" möglich."

Or, in English: "The combination of Vernam encoding (One-Time-Pad) and 
the patent-pending approach by T. Heidel enables "up to provably secure 
data encryption"."

Fun,

Stephan
