How are passwords sent to servers?
When the user enters a password, this is sent over the network and hashed on the server using a copy of the same hashing function. Some implementations of this scheme will hash the user’s password before sending it across the network to be compared with the hash stored on the server.
Is it safe to send credentials via email?
Why sending and receiving passwords via email is a bad idea You might be wondering why it’s a bad idea to share passwords via email and the answer is a very simple one — security. Emails are often sent in “clear” or “plain” text. If any one of those systems is compromised, it can reveal your password to hackers.
What is the most appropriate way to send a username and password from a client to a server using HTTPS?
You should always use HTTPS and avoid homebrewed code. SSL will take care of hashing & encryption. That is the ONLY secure method. Also ensure you’re hashing passwords on the server end and storing the hash, not the original password.
How to send passwords securely over the Internet?
You can use SRP to use secure passwords over an insecure channel. The advantage is that even if an attacker sniffs the traffic, or compromises the server, they can’t use the passwords on a different server. https://github.com/alax/jsrp is a javascript library that supports secure passwords over HTTP in the browser, or server side (via node).
Which is better to send credentials over HTTPS or HTTP?
In a nutshell, as @jeremy-powell mentioned, always favour sending credentials over HTTPS instead of HTTP. It will take away a lot of security related headaches. TSL/SSL certificates are pretty cheap these days.
Which is the most secure way to send username / password?
Use asymmetric encryption to do it, meaning use the public key (using public certificate part) where the receiver can decrypt only (he has the full certificate with private key). You could use a JWT as token to put it in and use JWE also,
What’s the best way to secure your server?
Another way to ensure secure communication is to use private and virtual private networks (VPNs), and software such as OpenVPN (see our guide on installing and configuring OpenVPN on CentOS ).
