php-password-hash

I have been scratching my head on this for over 2 hours. I have researched articles on stackoverflow including: Issue with Bcrypt not verifying correctly php password_hash and password_verify issues no match `password_verify` call returning false for correct password And I havent been able to correct my issue. I would appreciate some guidance on how much of an idiot I am being: Function to insert data into MySQL database: function insertUser($userObj) { $query = $this->databaseConnection->getStntPrepare()->prepare( "INSERT INTO user(username, userpassword) VALUES (?,?);"); $username = $userObj

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? 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 future, whereupon PASSWORD_DEFAULT will always be used to apply the strongest supported hashing algorithm. Cost

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 hashing with a salt as follows: "$2a$", "$2x$" or "$2y$", a two digit cost parameter, "$", and 22

I am trying to process a password as md5 into the database, this is the concerned code: include_once("config.php"); session_start(); if(isset($_POST['signup'])){ $name = $_POST['name']; $email = $_POST['email']; $pass = $_POST['pass']; $insert = $pdo->prepare("INSERT INTO users (name,email,pass) values(:name,:email,:pass) "); $insert->bindParam(':name',$name); $insert->bindParam(':email',$email); $insert->bindParam(':pass',$pass); $insert->execute(); }elseif(isset($_POST['signin'])){ $email = $_POST['email']; $pass = $_POST['pass']; $select = $pdo->prepare("SELECT * FROM users WHERE email='

I am trying to use the password_hash() function in my website, and I am getting an error Call to undefined function password_hash(). I checked my Server Details in GoDaddy, and my current version of php is 5.4. How can I fix this? John Conde password_hash() is not available in PHP 5.4. It is a new feature in PHP 5.5. In the meantime you can use this compatibility pack replacement . Compatibility pack sidenote: This library requires PHP >= 5.3.7 OR a version that has the $2y fix backported into it (such as RedHat provides). Note that Debian's 5.3.3 version is NOT supported. For versions not

What is the maximum password length I can use with PHP 5.5 password_hash() and password_verify() ? ircmaxell Ok, let's go through this. The function does have a password length limit. Just like all strings in PHP, it is limited to 2^31-1 bytes. To be clear, there's no way for PHP to deal with anything larger than that (today at least). So the function itself is limited. But what about the underlying crypto algorithms. BCrypt is limited to processing the first 72 characters of password. However, this is not commonly a problem as explained in this answer . So in short, yes it does have an

The new password_hash API in PHP 5.5 is nice and I'd like to start using it everywhere. Given an older project with an older database where passwords are stored in md5 hashes, what is the best way to go about migrating old user passwords to the new, more secure API? Apart from simply prompting users to reset their password upon next login (this is impractical and annoying for users) I've thought about the possibility of using current md5 hash as the input to password_hash() for all my existing users. To verify passwords for these users (during login), I'd convert their input to an md5 hash and
