Re: md5 crypt question

not sure if you've gotten any help on this yet. perhaps test the CRYPT_SALT_LENGTH and CRYPT_MD5 constants to make sure that your system and compiled php support md5 via crypt(). also, what salts did you try? note the comments at the bottom of http://php.net/manual/en/function.crypt.php about double-quoting $1$ and how it may be interpreted and how to escape the $ characters. also, i'm not sure if you need a $ character at the end of the salt string like in some of the examples on those comments or not. unfortunately, i don't have a system with php running right now to test. you may also want to investigate http://php.net/manual/en/ref.mhash.php depending on what kind of functionality you need. my guess is that crypt() would be suitable for you if it worked properly. -tcl.
