4. Digest authentication with Apache2

Since Basic Authentication, a well-known authentication authorization method for http, sends authentication information in plain text, there is a risk of ID and password leakage if the packet is intercepted.
On the other hand, Digest Authentication encrypts and transmits authentication information, so there is almost no risk of information leakage.

4.1 Create password file for Digest authentication

Specify an authenticated area called realm. This realm allows the same directory to be accessed as authenticated.
For this example, the realm is "DigestAuth" and a user and password file named "secretuser" ".digestauth" is created.

Confirmation

As above, secretuser and encrypted password are created

4.2 Edit Apache configuration file

Specify the directory to which Digest authentication will be applied. (In this case, specify the "secret" directory.)

Add the following at the end

Enable Digest authentication and reboot

When accessing http://<domain name>/ with a browser, a screen appears asking for "user name" and "password".
