Whoever suggested that encryption keys were "logic"? Some of the points in
this discussion have degenerated into logical fallacies (i.e.
https://yourlogicalfallacyis.com/) which would be a waste of time to
respond to. Perhaps the only thing left for me is to summarize my position.

The catch phrase "security by obscurity" has become a widely used figure of
speech which is intended to ridicule, even though obscurity is the
essential objective of data encryption and an essential objective of the
protection of data and keys. It has been somewhat entertaining for me to
point out the incongruities.

There is a huge ecosystem based on the adoption of products and services
which are based on publicly disclosed encryption algorithms who employ
people to make all sorts of distortions of things such as Kerckhoff's
tenets of cryptography.

1. The system must be practically, if not mathematically, indecipherable;
2. It should not require secrecy, and it should not be a problem if it
falls into enemy hands;
3. It must be possible to communicate and remember the key without using
written notes, and correspondents must be able to change or modify it at
will;
4. It must be applicable to telegraph communications;
5. It must be portable, and should not require several persons to handle
or operate;
6. Lastly, given the circumstances in which it is to be used, the system
must be easy to use and should not be stressful to use or require its users
to know and comply with a long list of rules.


How did they twist any of those tenets into a call for public disclosure
and discussion of encryption algorithms?

Rather than publicly disclose and debate "algorithms", why not simply
disclose the interface to algorithms (i.e. parameters) and invite hackers
to try to break them (discover, reverse-engineer, make them publicly
available)?

Reports of such attempts would disclose the strength or weakness of
algorithms, without disclosing the algorithms themselves.

The call for public disclosure of algorithms is more of a marketing
strategy, than a best practice for security.
