kandi X-RAY | hpkp Summary
This header has been deprecated citing risks of misuse, and therefore is not recommeded. This module (hpkp) will not receive any new feature development but will still be maintained. Adds Public Key Pinning headers to Express/Connect applications. To learn more about HPKP, check out the spec, the article on MDN, and this tutorial. Be very careful when deploying this—you can easily misuse this header and cause problems. Chrome has dropped support for HPKP citing risks of misuse. Setting reportOnly to true will change the header from Public-Key-Pins to Public-Key-Pins-Report-Only. Don't let these get out of sync with your certs! It's also recommended to test your HPKP deployment in reportOnly mode, or alternatively, to use a very short maxAge until you're confident your deployment is correct.

I want to configure a proxy with Nexus for a private repository in cloudsmith.io. When I configure the proxy with the public npm registry everything works good, but when I configure the proxy with the Cloudsmith repository the command npm install fails.
To authenticate with Cloudsmith (without proxy), the .npmrc file must contains this:

Answered 2019-Jun-27 at 16:32The answer is that Sonatype Nexus expects the upstream request to be challenged with a "401 Unauthorized" response + a valid WWW-Authenticate header, rather than a "404 Not Found" response.
The indication that this is the issue is in the log output at:

In the following code sample, I start a proxy server using HTTP::Proxy
and attempt to use it to request an HTTPS URL, but the proxy server either doesn't actually make the request, or doesn't return the response. However, if I make the URL use HTTP (not secure), the request succeeds. I've installed both IO::Socket::SSL
and LWP::UserAgent::https
(yay secret deps!), but am still unable to get HTTPS requests to go through the proxy. How can I get HTTP::Proxy
to work with HTTPS URLs?
Here's my code:

QUESTION
I have been trying for a few days (using other answers on this site and MathWorks ) to get around the crumb
that Yahoo Finance add at the end of a link to download a CSV file, e.g. for a CSV with Nasdaq100 data in a Chrome browser you would get the link: https://query1.finance.yahoo.com/v7/finance/download/%5ENDX?period1=496969200&period2=1519513200&interval=1d&events=history&crumb=dnhBC8SRS9G (by clicking on the "Download Data" button on this Yahoo Finance page).
This crumb=dnhBC8SRS9G
obviously changes depending on Cookies and User Agent so I have tried to configure MATLAB accordingly to disguise myself as a Chrome browser (copying the cookie/user agent found in Chrome):
ANSWER
Answered 2018-Jun-13 at 07:26Okay, did some playing around with this with Curl and it appears that what you are trying to do is not possible at that specified URL. Worth noting is that the crumb and the cookie change often, so I had to parse the response of the two GET requests every time I ran the script to get the their values.
I'll walk you through my attempt.
- GET request and save cookie file.
- Parse cookie file for cookie.
- Print cookie to file.
- GET request and save html.
- Parse HTML and obtain crumb.
- Form URL.
- Form curl request.
- Execute request.

QUESTION
Imagine a scenario where a client application is sending a password to a backend server so that the server can validate that the user entered the correct password when being compared to a stored variation of the password.
The transport mechanism is HTTPS
with the server providing HSTS
& HPKP
to the user agent and strong cryptographic ciphers being preferred by the server scoring A+ on SSL labs test. None the less, we may wish to avoid sending the original user provided password to the server from the user agent. Instead perhaps we'd send a hash after a number of rounds of SHA-256 on the client.
On the server-side, for the storage of passwords we are using bcrypt with a large number of rounds.
From a cryptographic point of view, is there any disadvantage to performing bcrypt on the already sha-256 hashed value as opposed to directly on the plain text password? Does the fixed length nature of the input text when using hashes somehow undermine the strengths of the algorithm.
EDIT: I'm not asking about performance such as the memory, CPU, storage requirements or wall clock time required to calculate, store, sent or compare values. I'm purely interested in whether applying a hash prior to applying bcrypt could weaken the strength of bcrypt in the case of a disclosure of the full list of stored values.

QUESTION
I'm looking for a performance comparison between a connection to one server with "classic" tls (no hpkp enabled) and another one with tls with hpkp enabled. Where I can find these information or where can I find steps or a guide to follow?
Any help would be highly appreceated.
...ANSWER
Answered 2017-May-14 at 18:11HPKP only consists of an additional check which compares the fingerprint of the public key in the certificate against a known value. This is a very cheap operation compared to all the other operations which need also to be done on a full TLS handshake, like:
- validating the certificate chain is more expensive than checking the fingerprint only
- key exchange is way more expensive then validating the certificate chain
- and the costs of communication are usually way higher unless you have a low-latency connection or a very slow CPU
In summary: you will probably not be able to measure any performance impact caused by HPKP.
