4. Digest authentication in Apache2

Since Basic Authentication, a well-known authentication authentication method for http, transmits 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 the authentication information and sends it in encrypted form, 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.
As an example, we will create a user named "secretuser" and a password file ".digestauth" with "DigestAuth" as the realm. Execute the following command and enter the password for "secretuser" when prompted.


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

Create a directory for Digest authentication

Enable Digest authentication and reboot

When accessing http://[FQDN]/secret with a browser, a screen appears asking for "user name" and "password".
