Re: [PHP-DEV] hash_hkdf() signature and return value

Hi Dan,

Sorry for keep posting broken English.

I shouldn't difficult.

Looking forward more than handful, useful and common hash_hkdf()
application
examples for PHP that justify the API. If you would not like to spend time
for working
code, just ideas are OK also.

Regards,

Yasuo

Hi Dan,

I appreciate your feedback, regardless of your opinion towards this issue.

OK. It is recorded that you think current API is totally valid.
I'm not sure who is "us". Please reply and record your opinion.

Well, my thoughts are not totally my inventions.

For HKDF, it came from the RFC 5689 basically.

For input validations, it is originated in Defensive Programming. Defensive
Programming is referred in early 90's AFAIK, it is called secure programming
or secure coding now. I believe the basic idea was developed 60's computer
scientists who researched program execution correctness verification
methods.

Did you really read the RFC 5689?
Please mention what is wrong with my statements if you think my statements
are totally wrong.  It should be easy to point it out, since I provided
many points.
This is technical list, not political list nor religious list after all.

I should note that no valid code example was presented that justifies
current API.

Not a single valid code example, yet.

This fact infers what you say "us" have concrete reason(s) that supports
current API validity.

Please provide undisclosed valid code example that would be more common
than CSRF token and API token derivations. There are even more URL singing,
etc in
my PHP RFC.

If any one of you provided example usages that would be common, valid
(and optimal, it should be optimal since HKDF is designed for the best
possible derived key with HMAC), I would not raise this issue again.

Sorry  but, I'm not liking the vote result.
I'm frustrating the fact there is no code example(s) justifies current API
design
that is insecure and inconsistent.

It's totally new module.
I already replied to your comments in other thread.
Apparently, you are ignoring single responsibility principle.
Please take into the principle into your thoughts.

This pattern of behaviour, continually refusing to accept that other

As I wrote _MANY_ times in past mails.
I would have stopped discussion, if there are example codes that
justify the API.

Sorry for repeating requests, but this is technical list and no evidence
is provided.

If you really think my statements are wrong. Please comment
each line by replying "wrong" so that your idea becomes more clear.
I shouldn't difficult.

I provided more than handful valid use cases in my PHP RFC.
The technical evidence should not be difficult.
It's just example(s).

I'm waiting.

Not us, you.

You should start listening to other people's feedback.

You continually refuse to accept any feedback that doesn't agree with
your world-view, not only on the subject of hkdf, but on validation
and other things you think are "MANDATORY"

You should respect RFC votes and stop bringing up the same discussions
over and over again. This is incredibly tedious.

In particular your suggestion about hash_hkdf was rejected
unanimously, apart from your own vote
https://wiki.php.net/rfc/improve_hash_hkdf_parameter and so probably
shouldn't be brought up for discussion, except if you can bring new
facts for discussion.

"Not liking the result of the vote" is not a new fact to discuss.

Additionally though, your ideas about adding validation/filter
functions as a C extension, rather than implementing them in PHP have
also been resoundingly rejected,
https://wiki.php.net/rfc/add_validate_functions_to_filter and yet you
continue to promote the idea. This is also tedious.

This pattern of behaviour, continually refusing to accept that other
people have opinions that don't align with yours, and continually
bringing up the same topics for discussion over, and over, and over
again is not productive. It does not make people want to engage you in
discussion, as it is a waste of their time. This is not something
other people can fix for you.

cheers
