After knowing that hashing a password is my choice for making a login form. Now I am facing another issue - sha1, sha256 or sha512?This is a standard method using salt I think I got it from a reference book of mine,\[code\]# create a salt using the current timestamp$salt = time();# encrypt the password and salt with SHA1$usr_password = sha1($usr_password.$salt);\[/code\]but then after I have done some research on sha1, it was told it may not be so secure in the future, suggesting using hash().But I don't quite understand using hash() - for instance - \[code\]$usr_password = hash('sha256', $usr_password); \[/code\]what is that 'sha256' or 'sha512' which I found it here?http://hungred.com/useful-information/php-better-hashing-password/can I put anything instead, like '@123'?why is it called salt anyway - $salt = time(); is nothing else but just a unix timestamp isn't it?thanks!
