Advanced .htaccess Tricks for Securing Sites

This is all new, experimental, and very very cool. It literally uses .htaccess techniques to create several virtual “locked gates” that require a specific key to unlock, in a specific order that cannot be bypassed. It uses whitelisting .htaccess tricks to specify exactly what is allowed, instead of trying to specify everything that isn’t allowed. Also, by setting specific cookies/tokens after successfully passing through a gate, we can then require the exact cookie/token from the previous gate, which stops an attacker from skipping or bypassing gates.

.htaccess Plugin Blocks Spam, Hackers, and Password Protects Blog

Well what can I say, other than this is sooo DOPE! Here is a list of the modules this plugin (version 4.7 unreleased) will automatically detect. I compiled the list myself using every module included with any default Apache installation for ALL the versions listed below, 1.3 to 2.2+

Want to know something else I’m including in this plugin? For each and every module that is detected, this plugin can then detect ALL of the modules .htaccess Directives! For instance, RewriteRule, AccessFileName, AddHandler, etc.. are each a directive belonging to a module that is allowed to be used from within .htaccess files.

Talk about sick.. these tricks have the diamond disease!

.htpasswd file Generator

.htpasswd is a flat-file used by Apache and other applications to store usernames and password for HTTP authentication. Apache .htpasswd files may contain multiple types of passwords; some may have MD5-encrypted passwords while others in the same file may have passwords encrypted with crypt(3) and/or SHA-1. Usernames are limited to 255 bytes and may not include the character :.
Htpasswd Formats
Apache Servers recognize 4 formats for representing a password hash in the text file usually named .htpasswd.

CRYPT
crypt(3) is the library function which is used to compute a password hash. Technically the name is a misnomer since it is actually a cryptographic hash function. The output of the function is not merely the hash: it is a text string which also encodes the salt and identifies the hash algorithm used. Apache uses the traditional Unix crypt function with a randomly-generated 32-bit salt (only 12 bits used) and the first 8 characters of the password. ALG_CRYPT
MD5
MD5 is one in a series of message digest algorithms designed by Professor Ronald Rivest of MIT. The 128-bit (16-byte) MD5 hashes (also termed message digests) are typically represented as a sequence of 32 hexadecimal digits. In .htpasswd files the hash is: $apr1$ + an Apache-specific algorithm using an iterated (1,000 times) MD5 digest of various combinations of a random 32-bit salt and the password. ALG_APMD5
SHA-1
The SHA hash functions are a set of cryptographic hash functions designed by the National Security Agency (NSA) and published by the NIST as a U.S. Federal Information Processing Standard. SHA-1 produces a 160-bit digest from a message with a maximum length of (264 − 1) bits. SHA-1 is the most widely employed of the SHA family. It forms part of several widely used security applications and protocols, including TLS and SSL, PGP, SSH,…

.htaccess – Wikipedia

.htaccess (Hypertext Access) is the default name of Apache’s directory-level configuration file. It provides the ability to customize configuration directives defined in the main configuration file. The configuration directives need to be in .htaccess context and the user needs appropriate permissions.

Statements such as the following can be used to configure a server to send out customized documents in response to client errors such as “404: Not Found” or server errors such as “503: Service Unavailable” (see List of HTTP status codes):
ErrorDocument 404 /error-pages/not-found.html
ErrorDocument 503 /error-pages/service-unavailable.html
When setting up custom error pages, it is important to remember that these pages may be accessed from various different URLs, so the links in these error documents (including those to images, stylesheets and other documents) must be specified using URLs that are either absolute (e.g., starting with “http://”) or relative to the document root (starting with “/”). Also, the error page for “403: Forbidden” errors must be placed in a directory that is accessible to users who are denied access to other parts of the site. This is typically done by making the directory containing the error pages accessible to everyone by creating another .htaccess file in the /error-pages directory containing these lines:
Order allow,deny
Allow from all
Contents
[hide]

1 Password protection

1.1 Password unprotection
1.2 Extra secure method to force a domain to only use SSL and fix double login problem

2 Enable SSI
3 Deny users by IP address
4 Change the default directory page
5 Redirects
6 Prevent hotlinking of images

6.1 From specific domains
6.2 Except from specific domains

7 Standardise web address to require www with SEO-friendly 301 Redirect
8 Directory rules
9 User permissions
10 Other uses
11 See also
12 External links

Password protection
Make the user enter a name and password before viewing a directory.
AuthUserFile /home/newuser/www/stash/.htpasswd
AuthGroupFile /dev/null
AuthName “Protected Directory”
AuthType Basic
<Limit GET POST>
require user newuser
</Limit>
The same behavior…
