Re: [WEB SECURITY] username & pw in clear-text through SSL considered safe?



What you're asking is not possible. Without a proper context (i.e.
security budget, attack model, other competing issues) we can only
theorise.

I believe I've demonstrated that there are situations where such a
feature increases security. I can't do what you're asking me to do,
which is demonstrate that a feature is appropriate in every situation.
Benefit is subjective. I can't argue for a feature without a context
(e.g. security budget, competing issues, attack model, etc).
