What protocol sends passwords without encryption?
Password Authentication Protocol (PAP) is a weak authentication protocol. It does not encrypt any data and the authentication credentials are sent in the clear.
Is Digest access authentication secure?
Digest authentication is secure due to the way it passes authentication information over the network. Usernames and passwords are never sent. Instead, IIS uses a message digest (or hash) to verify the user’s credentials.
What is the difference between basic and digest authentication?
4 Answers. Digest Authentication communicates credentials in an encrypted form by applying a hash function to: the username, the password, a server supplied nonce value, the HTTP method and the requested URI. Whereas Basic Authentication uses non-encrypted base64 encoding.
Which is more secure clear text password or digest authentication?
Most browsers support SSL/TLS and most sites which require sensitive information such as credit card information use SSL/TLS today. The use of an encrypted channel or key exchange is always more secure than clear text passwords or Digest Authentication. It is important to correctly use SSL/TLS.
Is it possible to store passwords in HTTP Digest?
Unfortunately, there are many problems with HTTP-digest and the most glaring of them is that the server needs to have the password in cleartext. So while it’s possible to communicate passwords securely using HTTP, it’s not possible to securely-store passwords on the server while using it.
How does digest authentication work in HTTP 1.0?
Digest Authentication acts as an extension to HTTP 1.0 and provides an authentication method that does not transmit the password over the network. Instead the password is treated as a secret input to a digest algorithm. The resulting digest is transmitted and verified by the server.
Can you send information over an unsecure channel?
You can’t. To securely send information over an unsecure channel, you need encryption. Symmetric encryption is out, because you would first need to transport the key, which you can’t do securely over an unsecure channel [*]. That leaves you with public key cryptography.
