ID: 53789 User updated by: richard at blueapex dot co dot uk Reported by: richard at blueapex dot co dot uk Summary: Setting session.hash_function doesn't change hash function used. -Status: Feedback +Status: Open Type: Bug Package: Session related Operating System: Freebsd 8.1 PHP Version: 5.3.5 Block user comment: N Private report: N New Comment: I have the hash extension enabled. Doing print_r(hash_algos()) gives a fair few hashes. I'm using hash('SHA512', $foo) for encrypting passwords so it defiantly is available to PHP. Previous Comments: ------------------------------------------------------------------------ [2011-02-01 14:39:16] il...@php.net Do you have the hash extension enabled? Without that extension, hashing algorithms other than md5/sha1 will not be available. ------------------------------------------------------------------------ [2011-01-30 14:07:14] datahell at elxis dot org I face the same problem on PHP 5.2.5 (x64) on my local installation Windows Vista 64bit. ------------------------------------------------------------------------ [2011-01-19 14:23:34] richard at blueapex dot co dot uk Description: ------------ This may be an apache bug, though I'll start with putting it down as php. There is a similar bug: Bug #49469 submitted in 2009 with advice try the latest snapshot, that was version 5.3.0 and I'm using version 5.3.5 so assuming that advice isn't valid and the bug still exists. Setting session.hash_function variable in php.ini doesn't change the value used to generate the hash function. I've tried sha512, sha1, whirlpool. All of these don't change the hash delivered to the browser (PHPSESSID) and still the standard md5() hash is used. All the hash algos tried are on the system when the output of hash_algos() is examined. Specifying 1 does make the system use SHA1 to generate the session hash. ############################## Revelant. php.ini session.save_handler = files session.use_cookies = 1 session.use_only_cookies = 1 session.name = PHPSESSID session.auto_start = 0 session.cookie_lifetime = 0 session.cookie_path = / session.cookie_domain = session.cookie_httponly = session.serialize_handler = php session.gc_probability = 1 session.gc_divisor = 1000 session.gc_maxlifetime = 1440 session.bug_compat_42 = On session.bug_compat_warn = On session.referer_check = session.entropy_length = 0 session.entropy_file = session.cache_limiter = nocache session.cache_expire = 180 session.use_trans_sid = 0 session.hash_function = sha512 session.hash_bits_per_character = 5 url_rewriter.tags = "a=href,area=href,frame=src,input=src,form=fakeentry" Test script: --------------- session_start() Expected result: ---------------- sha512 generated PHPSESSID Actual result: -------------- md5 generated PHPSESSID ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/bug.php?id=53789&edit=1
