Alice and Bob could try to bypass this by encrypting the connection. However, Alice doesn't know whether the encryption was set up by Bob, and not by Mallory by doing a man-in-the-middle attack. Therefore, Alice sends a hashed version of her password instead, like in CRAM-MD5 or DIGEST-MD5. As it is a hash, Mallory doesn't get the password itself.
Here's what to know about gargling with salt water—and the right ratio of salt to water to use—to ease the pain of a sore throat. Get ready to start mixing, because even though it might not ...
For instance, the Cisco IOS originally used a reversible Vigenère cipher to encrypt passwords, but now uses md5-crypt with a 24-bit salt when the "enable secret" command is used. [33] These newer methods use large salt values which prevent attackers from efficiently mounting offline attacks against multiple user accounts simultaneously.
In cryptography, CRAM-MD5 is a challenge–response authentication mechanism (CRAM) based on the HMAC-MD5 algorithm. As one of the mechanisms supported by the Simple Authentication and Security Layer (SASL), it is often used in email software as part of SMTP Authentication and for the authentication of POP and IMAP users, as well as in applications implementing LDAP, XMPP, BEEP, and other ...
Digest access authentication is one of the agreed-upon methods a web server can use to negotiate credentials, such as username or password, with a user's web browser.This can be used to confirm the identity of a user before sending sensitive information, such as online banking transaction history.

To manage and recover your account if you forget your password or username, make sure you have access to the recovery phone number or alternate email address you've added to your AOL account. If you know your username but need to reset your password, make sure you create a strong password after you're back in your account.
The simplest example of a challenge-response protocol is password authentication, where the challenge is asking for the password and the valid response is the correct password. An adversary who can eavesdrop on a password authentication can authenticate themselves by reusing the intercepted password. One solution is to issue multiple passwords ...
