## #57435 — Anthony Ferrara — 2012-01-19T22:05:43+00:00

Hi all,

I've implemented a patch (attached to the bug, but in a gist as well
here https://gist.github.com/1641725 ) that implements a `hash_pbkdf2()`
function.  The patch also slightly refactors `hash_hmac()` to split out
a little bit of common functionality (since pbkdf2 relies upon hmac).

https://bugs.php.net/bug.php?id=60813

I've targeted the patch towards trunk for now, but I'd like to see if
it could get into 5.3 and 5.4 as well (in a point release).

Let me know your thoughts,

Thanks,

Anthony
