Password hashing not working in php mysql

由 大憨熊 提交于 2019-12-31 05:16:06
问题 I am trying to use password hashing using phpmysql. The issue is password_verify does not seem to work for me so far. Say, my password during registration is '123456789'. I stored it in database using password_hash('123456789', PASSWORD_BCRYPT, array('cost' => 12)); And then when I enter '123456789' in the login field, it does nothing, fails. Here is my code: <?php session_start(); include('db.php'); ?> <!DOCTYPE html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">

Comparing passwords to stored hash [duplicate]

问题 This question already has answers here : Secure hash and salt for PHP passwords (14 answers) Closed 4 years ago . From my understanding so far (at least I think) the password_hash() function generates a hash based on the algorithm in use, cost and the salt. While the password_verify uses the information provided from e.g. password_hash($pass, PASSWORD_BCRYPT, array('cost'=>10)) to check if the retuned value is true or false as it contains all the information necessary for verifying. I

Is PHP's password_hash FIPS compliant?

由 你离开我真会死。 提交于 2019-12-20 03:30:11
问题 I believe hash('sha256', $pw) is FIPS compliant, but I know for certain that an attack vector is possible with using that function. Also, there is no salt (so I would have to encounter that implementation and I would rather not). Is password_hash / password_verify FIPS compliant? 回答1: No. FIPS 140-2 does not certify password hashing algorithms. As such, password_hash cannot be FIPS compliant, because FIPS simply doesn't apply to it. To the best of my knowledge, the hash implementations used

PASSWORD_DEFAULT vs PASSWORD_BCRYPT

问题 What is the difference between PASSWORD_DEFAULT and PASSWORD_BCRYPT? Do they both use Blowfish encryption algorithm? What is cost in an algorithm? How to set up password_hash in PHP produce a 255-hash length instead of 60? 回答1: Currently PASSWORD_BCRYPT is the only algorithm supported (using CRYPT_BLWFISH), therefore there is currently no difference between PASSWORD_DEFAULT and PASSWORD_BCRYPT . The purpose of PASSWORD_DEFAULT is to allow for the inclusion of additional algorithms in the

Generating Password Hash In PHP 5.5 And Setting Cost Option

由 |▌冷眼眸甩不掉的悲伤 提交于 2019-12-18 14:15:56
问题 I know PHP 5.5 is in alpha but this class I am making is just being made in advance to utilize it's hashing feature by using function_exists(). I checked out the password_hash documentation. The 3rd argument is for $options which currently supports two options, 'salt' and 'cost'. It states the following: cost, which denotes the algorithmic cost that should be used. Examples of these values can be found on the crypt() page. When I go to the crypt() page the documentation it gives is: Blowfish

Password does not match after being encrypted using crypt() and password_hash() function

由 非 Y 不嫁゛ 提交于 2019-12-17 22:36:52
问题 I modified my old post. I tried the crypt() function and now trying to work with password_hash() and password_verify() to verify the encrypted password coming from database but on each call, password_hash() function retuns a different encrypted string and password_verify() cannot match it. This is how I am doing this. //please ignore the syntax error if any $data = '11'; $dbpass = password_hash($data, PASSWORD_BCRYPT); echo $dbpass; // displays the random strings on each page refresh.

PHP Warning: Use of undefined constant PASSWORD_ARGON2ID when using password_hash() in php 7.3

由 萝らか妹 提交于 2019-12-12 11:35:15
问题 I recently installed PHP 7.3.6 through Plesk's web GUI for a development copy of a web app, as I intend to update our production environment from php 7.0 to 7.3. I decided to take the opportunity to upgrade our password hashing from PBKDF2 to Argon2ID since the PHP core has it already included. I was surprised to get a warning stating that the PASSWORD_ARGON2ID constant is undefined, since I understand it was added in php 7.3.0. I tried searching for any instance of this error and the only

由 筅森魡賤 提交于 2019-12-12 11:19:46
问题 I've been searching around the internet for the best option to encrypt passwords for databases. I've found that password_hash() is the best option, but then I saw that it is only for PHP 5.5+. Apparently my host has version 5.3.27. And I've been searching for the best alternative but couldn't find anything good. 回答1: The library below gives you password_hash for php < 5.5 https://github.com/ircmaxell/password_compat.git 来源： https://stackoverflow.com/questions/20229058/best-alternative-for

Why is that? if it keeps doing that i will never

password_verify hash not matching password

由 心已入冬 提交于 2019-12-09 19:29:57
问题 I have generated a password hash using the code below: $hash = password_hash("test", PASSWORD_BCRYPT); I then store it in the database using a 255 char. Then I try to do the comparator to test the login and it fails. It only lets me login using a hash I have just generated a few lines before, not one stored in the database. <?php //Database connection require 'database.php'; //Handle logins if ($_POST['login']) { //Receive the login attempt $login_email = $_POST['login_email']; $login
