lol, read this (it is in english):

https://www.bsi.bund.de/EN/Topics/OtherTopics/Chiasmus/Chiasmus_node.html

you know that you deal with experts when you read this:

//Quote
Cryptographic details

The core of the program is the BSI's own symmetric block encipherment algorithm, Chiasmus. Chiasmus was specifically developed for software implementations. Chiasmus encrypts 64-bit blocks into 64-bit blocks, using a 160-bit key. Chiasmus for Windows/Linux uses Chiasmus in cipher block chaining (CBC) mode. The effective key length is 128 bits, the remaining 32 bits constituting a checksum.
//Unquote

The algo is not revealed, and neither are the sources as such, if course.
When I read this here:
//Quote
Chiasmus™ is an encryption program for Windows (Windows 95, 98, 2000, ME, NT 3.5.2 and higher, XP, Vista, 7, 8, 10) and Linux. Chiasmus is a 32-bit application, but it also runs on newer 64-bit operating sytsems (Windows 7, 8 and Linux). With Chiasmus it is possible to encrypt individual files or entire folders.
//Unqoute
I fear the worst. Something that still runs on Win95 ? I would love to get my hands on the code or the binaries. If somebody should have them, please post here.

For context: the BSI is a state organization from Germany, dealing with IT related matters, mostly as kind of consultants for the government and the public.

I'd like you to use my software, please prove to me that you're going to use it the way I say:

Conditions of use

Chiasmus may only be used where its use is in the interest of the Federal Republic of Germany. Details are set out in the license agreement.
Ordering
