Note Submitter: php at nospam dot nowhere dot com ---- The makesalt() function code below when used to create an MD5 salt, produces a salt with characters not typically in a salt used by operating system crypt functions. Some of these characters may have unintended side effects depending on how they are used - including the following: @ ` ~ \ | {}. I am using the following to create MD5-Crypt hashes, (yes, I am assuming CRYPT_MD5 support is present). <?php function md5crypt($password){ // create a salt that ensures crypt creates an md5 hash $base64_alphabet='ABCDEFGHIJKLMNOPQRSTUVWXYZ' .'abcdefghijklmnopqrstuvwxyz0123456789+/'; $salt='$1$'; for($i=0; $i<9; $i++){ $salt.=$base64_alphabet[rand(0,63)]; } // return the crypt md5 password return crypt($password,$salt.'$'); } ?>
