Many hash iterations: append salt every time?

Question

I have used unsalted md5/sha1 for long time, but as this method isn\'t really secure (and is getting even less secure as time goes by) I decided to switch to a salted sha512

Answer 1

Please please please do not roll your own crypto. This is what libraries like OpenSSL are for. Here's few good examples of how you would use it to make salted hashes.
