Πληρωμή κατά την παράδοση
I have a PHP website linked to a very old MS SQL database that still stores member passwords as plain text. I need to update this so that the passwords are updated as encypted but also so that existing members are still able to log in without any problems. New members passwords website would also need to be encrypted. The PHP website's recover password feature might also need to be updated as it currently just sends the plain text password to the member but it would now need to get the member who'd forgotten their password to set a new password. The database/web developer needs to be based in the UK or at least the EU.

Perfect, I can do it. I'm Michele Cimmino, Italian software engineer and full stack web developer with above 8 years of experience in PHP. I'm a specialist of web security and I perfectly know all algorithms for safe password hashing in PHP. I can perform it for 1550GBP this weekend and deliver it on sunday evening or monday morning if we start now. An extra service I could provide is also prevent SQL injection introducing prepared statements everywhere, it would have an additional cost of 3000 GBP and require almost 2 week to be properly maintained and tested. Feel free to contact me on chat, I'll remain at your disposal. Kind regards

Hi, I am PHP/database coder and would like to help you encrypting the plain passwords. I did this kind of job before and can finish your project within very short time. I recommend to encrypt all existing (plaintext) passwords in your database with MD5. We can do this by using a script. Note: The passwords will not change. For example: Password 'test123' will be encrypted to 'Jx47&gi46', but the user will still login with his password 'test123'. Therefore we also need to modify the login script. No big deal! For resetting the password the user needs to enter his email. He will receive an email with a link to change his password. When he clicks the link he will be redirected to your website and can set a new password. I'll deliver clean, secure and accurate PHP code. Feel free to contact me for any questions. Sincerely, Ozzy

Hi. I propose to use the 'bcrypt' scheme for encrypting the passwords. This includes a 'salt' plus a user-configurable number of hash rounds to mitigate against bruce-force attacks. There is a PHP implementation. I have used bcrypt in 5+ projects previously and it is reasonably straight forward to implement. To allow existing users to log in with their old passwords - here are two tentative options to detect whether or not the user has updated to the newer password format ... 1) Add a boolean column to the user table indicating whether or not they have changed their password yet. 2) Simply examine the format of the password field. (Bcrypt-encrypted passwords have a distinctive format and length.) If they have updated to the new format, use the Bcrypt algorithm to check their password when they try to log in; if not, then allow them to log in, but urge them to set a new password as soon as possible. My DB experience is mainly with PostgreSQL and MySQL rather than MS SQL, but as long as your SQL code is mainly SQL-standard compliant I don't think this will pose a problem. I am based in Ireland.

Good afternoon, I'm a Scottish web developer who has been creating sites for over 10 years. I have made a range of websites for business: restaurants, travel sites and non-profits. I'm also employed to look after, maintain and update websites on a month-to-month including member sites with full password recover. Using PHP and MySQL I will update all your passwords in the database. This will include a salt to help with security. I will add this check to the login PHP functions so users won't have to edit their password. I'll also need to update the password recover function. Users will be sent an email asking to update their password at a special link. When entering a new password, this new password would be encrypted and saved. Please message me so we can discuss further or feel free to send me a message if you have any further questions or concerns. I’ll be more than happy to answer them for you. Hope to hear from you soon, Mark ,
