I am trying out a new function from PHP 5.5 called password_hash(). No matter what i do the $hash and the $password wont match. $password = "test"; $hash = "$2y$10$fXJEsC0zWAR2tDrmlJgSaecbKyiEOK9GDCRKDReYM8gH2bG2mbO4e"; if (password_verify($password, $hash)) { echo "Success"; } else { echo "Error"; } The problem with your code is that you are using the double quotation marks " instead of the single quotation marks ' when dealing with your hash. When assigning: $hash = "$2y$10$fXJEsC0zWAR2tDrmlJgSaecbKyiEOK9GDCRKDReYM8gH2bG2mbO4e"; It's making php think you have a variable called $2y and

I'm making a login system, and I want to hash the passwords to make them more secure, but it returns a different hash every time, and can't even be verified using password_verify(), here is my code: $password = password_hash($password4, PASSWORD_DEFAULT); and here is my code for verifying: if(password_verify($password4, $dbpassword)) So let's take it one part at a time but it returns a different hash every time That's the idea. password_hash is designed to generate a random salt every time. This means you have to break each hash individually instead of guessing one salt used for everything and

问题 According to manual: password_hash this function can be used for (PHP 5 >= 5.5.0) After searching for an alternative way I found this simple function from here: http://www.sitepoint.com/password-hashing-in-php/ function generateHash($password) { if (defined("CRYPT_BLOWFISH") && CRYPT_BLOWFISH) { $salt = '$2y$11$' . substr(md5(uniqid(rand(), true)), 0, 22); return crypt($password, $salt); } } I can manage my code by using function_exists before using, but My question is about above alternative

问题 My php code generates a hash using password_hash which I store in a database. Below is the PHP code: $hash = password_hash($value, PASSWORD_BCRYPT, array('cost' => $cost)); I would like to verify / check the password against this hash in nodejs. I saw lot of node modules (bcrypt, phpass, node-bcrypt), but all of them give me false. Below is sample hash generated in php and which I m trying to verify in nodejs. var hash = '$2y$08$9TTThrthZhTOcoHELRjuN.3mJd2iKYIeNlV/CYJUWWRnDfRRw6fD2'; var

PHP password_hash() password_verify() maximum password length?

问题 What is the maximum password length I can use with PHP 5.5 password_hash() and password_verify() ? 回答1: 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,

Converting md5 password hashes to PHP 5.5 password_hash()

问题 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

PHP password_hash(), password_verify()

你离开我真会死。 提交于 2019-11-26 14:44:57
My registration script accepts a user's password and then uses PHP's password_hash function to encrypt the password, then places it in a database. When I go to login using the just created user, I'm getting the error that checks if the passwords are the same or not. In my case, they're not. What am I doing wrong when I make the call to the password_verify function in the login script? REGISTER if($_SERVER["REQUEST_METHOD"] == "POST"){ function secure($data){ $data = trim($data); $data = stripslashes($data); $data = htmlspecialchars($data); return($data); } $p_num = secure($_POST["p_number"]);
