Generate SHA256 in php4

Hello all

How can I generate the SHA256 of a string in php4 ?

Regards

Use the PECL hash extension (http://pecl.php.net/package/hash). A quick Google search using your question also yielded this set of classes (http://forums.devnetwork.net/viewtopic.php?t=32334). By the way, you can avoid all of this by just upgrading to PHP5 since it's included by default, and PHP4's end of life is in just over 7 weeks.
