Howdy! I have gone through your point of query with your website, you need to change the encryption type from MD5 to SHA 256.
i have few set of question which will help me estimate the time duration of the project:
On which platform your website is being developed?
Can you share me few code snippets to have better vision towards the work?
Though, this is very short description, i will require some brief information about how much data is to be encrypted.
Being an experienced web developer, having a consistent rich experience of 12 years, worked with server side scripting languages like PHP and C#, Framework like Codeignitor, Cake PHP, Zend, Yii & Others, also in opensource i have worked with wordpress, joomla, magento and others.
Hence I myself feel capable to serve you with a quality work for you on time.
My job target is to provide 100% quality, I always focus on clients comfort and excellence. Brand positioning is equally important as other business development activities. I'd be glad if we can have further discussion about this project.
Thanks and Kindest regards.
