MD5 & Security Questions.

[Tom_Cash]

I've googled the web and this site, but not found what I want to know. So here goes...

1. Is MD5 free?
2. If so, how and where?
3. If not, is there any sort of encryption I can use for free?

Sorry if this sounds really nooby.

Kindest regards,
Tom.

1. Yes.
2. There are functions available to you to create MD5 hashes. One such PHP function is md5 [php.net].
3. There are others available for you, also. You can use sha1 [php.net], or the mcrypt [us2.php.net] functions, to name a few.

Thanks for the prompt reply! Very concise!

Fyi, sha512 is more secure than md5 and sha1.

If your version of PHP allows it, try,

hash("sha512", $string);

What version of PHP allows it? Do you know?
