+	:returns:	string
+
 Generates a random string based on the type and length you specify.
 Useful for creating passwords or generating random hashes.
 
 The first parameter specifies the type of string, the second parameter
 specifies the length. The following choices are available:
 
-alpha, alunum, numeric, nozero, unique, md5, encrypt and sha1
+alpha, alunum, basic, numeric, nozero, md5 and sha1
 
 -  **alpha**: A string with lower and uppercase letters only.
 -  **alnum**: Alpha-numeric string with lower and uppercase characters.
+-  **basic**: A random number based on ``mt_rand()``.
 -  **numeric**: Numeric string.
 -  **nozero**: Numeric string with no zeros.
 -  **unique**: Encrypted with MD5 and uniqid(). Note: The length
    parameter is not available for this type. Returns a fixed length 32
    character string.
+-  **md5**: An encrypted random number based on ``md5()``.
 -  **sha1**: An encrypted random number based on ``sha1()``.
