php - Is salting with a hashed version of the user's password just as secure as salting with a pre-defined string? -

-

basically, i'm asking if salting password appending hashed version of end of secure salting different string. so:

is this:

$pass = "pass"; $salt = sha1(md5($pass)); $pass = md5($pass.$salt);

as secure this?

$pass = "pass"; $salt = "4d9ds*^dkrui45^#dkd*3fd8&!dlvd*"; $pass = md5($pass.$salt);

the first example secure hashing without using any salt @ all, because still requires password , nothing more crack. in other words, applying hashing functions same thing few times more.

a better bet still create salt each user , store alongside, separately. fixed salt alright, guess, because cannot use password determine salt. however, generating unique salt each user better because take more information password crack (e.g. username, date registered, or other info).

i define tasks using nsdictionary, i'd save in plist file (i didn't have luck core data far), got stuck @ 2 points: -- when using initwithobjectsandkeys: can change data type number or boolean, using nsdate's numberwithint: , numberwithbool: methods, respectively. can't seem find method change type date though. couldn't find in documentation. -- second problem ran nested arrays. how can add them dictionary? i have uploaded picture here of trying achieve. thank in advance! do mean nsnumber 's +numberwithint: , +numberwithbool: methods, not nsdate ? it's nsnumber defines methods. to convert number date, depends on number is. if it's unix timestamp, [nsdate datewithtimeintervalsince1970:thetimestampinseconds] . as adding nsarray objects dictionary: [yourdictionary setobject:yourarray forkey:@"somekey"]; you'll have post code if need more question isn't clear.
