    Password Protect Webpages

    - We use the apache web server. To configure a directory for password protection do the following:

    1) (DONE on Legend): In the configuration file "httpd.conf" (on our server it's in /etc/httpd/conf)

    #
    # AccessFileName: The name of the file to look for in each directory # for access control information.
    #
    AccessFileName .htaccess


    2) In the directory you want to protect create ".htaccess"
    Contents of ".htaccess":

    authname "Research Notes"
    authtype basic
    authUserFile /home/astubbs/safedir/.htpasswd
    require valid-user

    3) Encrypt a password
    For example we use perl:
    $ perl -e 'print(crypt(frog,19));'; echo
    19BXtlId6awbo

    note:
    password is frog, two digit seed is 19


    4) Using the password you just encrypted, create ".htpasswd" in the directory you specified in for authUserFile in ".htaccess"
    Contents of "/home/astubbs/safedir/.htpasswd":
    anyone:19BXtlId6awbo

    5) Now the directory you placed ".htaccess" in is password protected

    I set up the following directory as described above
    http://legend.me.uiuc.edu/astubbs/research/


    The password gets sent to the server unencrypted so it's not extremely secure.
