passwords

问题 i want batch file to mask the input with * without extra file For example http://pastebin.com/2c4EtG4g this code is working successfully but it is very slow when i write the letter can any one give my code is fast and without an extra file ? or edit the code in the link to be fast ?? 回答1: Does this meet your "no extra file" criterion? It's a batch file that creates and deletes a tool to get the input, and so it is completely portable, and works in 64 bit machines too. Herbert Kleebauer wrote

问题 I am working on a game at the moment and all I want is my login screen to be able to check that the username and password I have already stored in my database is correct and when it is correct and the log in button is clicked to open a new activity. I have my database built and also a login I just need to figure out how to check against my database not just the text in the fields. I already have a pre-added login stored in the database: Username: test Password: 1234 Thanks in advance p.s I am

I look forward to helping of everyone Thanks for all :D trankinhly 回答1: Passwords in Active Directory are not retrievable. Nor are they in most directories. (eDirectory has a password policy, that if you bind as the

问题 This is my first attempt in securely storing passwords and I would like to make sure that everything is done correctly. I was advised to use SHA-256 hashing alongside salt. Assuming user submitted their password thorough form, we get the password via $password = $_POST["password"]; What is correct way to salt $password and use SHA-256 hashing on it, so it can than be stored in a password field "password CHAR(64)" in a database? Once done and stored how would I than compare value stored in a

问题 I would like to make sure that when user log in it will stay in session no matter what happens (crashed, shut down/power down/reboot, leaving the app) at same time the user info data will be sending with all the activities in the app to the webserver. for example at the start up of the app, user login '9999' it goes to the main activity that have 5 diff. activities. user 9999 will send one activity (i.e. gps location) it will send that info to the webserver as user 9999 gps 123.234 123.123. I

问题 I'm building a login system and I want to be sure I'm writing the write code to generate and store passwords in the db. $options['passwd'] is the string selected as a password by the user. This is my code to generate a hash: public function createPasswd($options) { $hash_seed = 'm9238asdasdasdad31d2131231231230132k32ka¡2da12sm2382329'; $password = $options['passwd']; $date = new DateTime(); $timestamp = $date->getTimestamp(); $rand_number = rand($timestamp,$timestamp + pow

问题 What is the "best" solution these today? This seems a good option: https://defuse.ca/php-pbkdf2.htm But then how about upgrading to PHP5.5 and using this? http://php.net/manual/en/function.hash-pbkdf2.php Curious as to why the PHP site states: Caution The PBKDF2 method can be used for hashing passwords for storage (it is NIST approved for that use). However, it should be noted that CRYPT_BLOWFISH is better suited for password storage and should be used instead via crypt(). For PHP versions

问题 I'm now using password stretching for all user account passwords throughout all my websites. In the db I store an iteration count and randomly assigned salt along with the final hash. I'm using SHA512 as the hash algorithm. I'm using C# in .Net 3.5 and 4.0 (dual framework library) for this. For accounts that only ever get randomly assigned passwords (things like web service API users etc) I keep the iteration count down to a range such that a password check takes no more than 1 second or so.
