Helper Hash

Name	Path
Hash Helper	/application/helpers/hash_helper.php

These encryption methods will do the base64 encoding and decoding for you. It is wise to use the base64 version of the encrypted string for database storage as there are no conflicting DB characters present and it can be decoded back to the raw hash easily.

Load the helper

$this->load->helper('hash_helper');

Methods

isStrong

Evaluates each letter of the string. It looks for at least one capital letter, one lower case and one numeric to return true.

$str	String	N/A	Yes	The string to evaluate.

Example

if (isStong($str) === true) {
    // Good for you
}

verifyHash

Compares a base64 encoded hash against a plain text string to see if they match. This function will base64 decode the encoded string for you and use it as a salt for comparisons.

Arguments

Variable	Type	Default	Required	Description
$str	string	N/A	Yes	The string to evaluate against
$hash	string	N/A	Yes	The base64 encoded, crypt string to use for the sale

Example
