I have been having some problems with hackers and as a result need to have my database backed up every 5 or 10 minutes. I know there is free software out there that can be installed and set up via a cronjob to run the backup. The software must be the type to save sql file in ftp and each time it runs will over-write the current last sql file so there is not a build up of hundreds of files.
I also need the passwords in the database encrypted BETTER THAN MD5 There is currently no encryption on passwords. Then I need a 4 digit PIN CODE added to 'user' table using same encryption.
Once we have that then we need the PIN system added to following pages for validation.
I will also need to FORCE all members to change their passwords and input a unique PIN CODE (as above) on next login, so that will need an additional field in the user table with status 0 or 1 as this will be a one time change, once they have gone through the one time change their status is set to 1 and don't have to change it again.
freelancer MUST know high security encryption. Please tell me what encryption system you will use when you bid. I will only consider bids with this info in the bid message.
Need this started asap.
