+PHP scrypt module
+=================
+
+[](https://travis-ci.org/DomBlack/php-scrypt)
+
+This is a PHP library providing a wrapper to [Colin Percival's scrypt implementation](http://www.tarsnap.com/scrypt.html). Scrypt is a key derivation function designed to be far more secure against hardware brute-force attacks than alternative functions such as PBKDF2 or bcrypt.
+
+Details of the scrypt key derivation function are given in a paper by Colin Percival, Stronger Key Derivation via Sequential Memory-Hard Functions: [PDF](http://www.tarsnap.com/scrypt/scrypt-slides.pdf).
+
+An example class using this module can be found in; scrypt.php

+PECL Install
+============
+
+This extension is now avaible through PECL.
+
+```
+pecl install scrypt
+```
+
+Build From Source
+=================
+
+Unix/OSX
+--------
+
+1. `phpize`
+2. If on OSX; `export CFLAGS='-arch i386 -arch x86_64'`
+3. `./configure --enable-scrypt`
+4. `make`
+5. `make install`
+6. Add the extension to your php.ini
+
+````
+ ; Enable scrypt extension module
+ extension=scrypt.so
+````
+
+Windows
+-------
+
+Using Visual Studio 2008 (or Visual C++ Express 2008) open up the attached project
+inside the VS2008 folder. This project assumes you have the PHP thread safe source at;
+`C:\phpsrcts\`, a PHP install at `C:\php\` and this source code extracted to
+`C:\php-scrypt\`.
+
+1. Build the project.
+2. Copy the resultant `scrypt.dll` to your ext directory in PHP.
+3. Add the extension to your php.ini
+
+````
+ ; Enable scrypt extension module
+ extension=scrypt.dll
