Restricting access to web pages and specific directories in Apache is usually done with .htaccess and .htpasswd files. This is not a tutorial on them – instead, this just describes the PERL functions that I wrote to help me out with altering .htpasswd files from a form. They are not very well written, but they worked well for a very small site.

If you have a site where there is just yourself or a small handful of people and you won't be editing the .htpasswd files a lot, feel free to use this script. If you need multiple people to be able to update the files simultaneously, you should add lockfiles or use a well-written PERL module to do the work for you.

To include it, just download auth.txt, save it as whatever you like (I like "auth.pm"), and then add require "auth.pm" to your PERL code. From there, you get access to a handful of functions.

%Data = LoadAuthFile(".htpasswd") - Loads the specified .htpasswd file into a hash. Returns the hash where $Data{'username'} = 'encrypted_pass'.

SaveAuthFile(".htpasswd", %Data) - Writes the users and passwords in the %Data hash to the file specified. Returns 1 on error, 0 on success.

MakeRestrictedFile("Directory/To/Protect", "/path/to/.htaccess", "Title For Prompt") - Writes a .htaccess file to the specified directory. Make sure to not include a slash at the end of the directory name. In the .htaccess file, it sets the AuthName (the prompt for the dialog box) to the "Title For Prompt", and tells to use any authorized user from the .htpasswd file specified. This function just makes it easy to password protect a directory.

$Encrypted = EncryptPassword("password") - Returns a crypt()'d password with a random encryption key. This is the type of password that is stored in .htpass files.

To use this, you load the .htpass file, delete or add hash entries, and then save the auth file. If you create entries, encrypt the password with EncryptPassword().
