Description:
------------
It would be realy usefull to include sha256 hashing function because md5 and sha1 aren't so secure nowdays. And there are a lot of sha256 implementations that can be used! So there is nothing new to invent :)

Thank you for your bug report. This issue has already been fixed
in the latest released version of PHP, which you can download at 
http://www.php.net/downloads.php

SHA1 is unsecure? I never have read anything like that. The news were only saying that some guys think that in theory it maybe possible to guess the keys in a reasonable time with a huge processing power if you new something about the hashed stuff. More or less the same goes for MD5 only it is shorter, so the computation power needed is less and knowing something about the hashed stff is worth much more than with SHA1.

Still having SHA256 would be good. Look for mhash. And look for extension mhash and MHASH_SHA256.
