Password verify php not working
I am using php 5.4 with this backwards compatibility script: https://github.com/ircmaxell/password_compat/blob/master/lib/password.php Show that shouldn't matter though, because I can get the hashing and verification process working in my registration function:
but whenever I try to store the hash in a MySQL database and then retrieve it for the verify function, it always fails. Here is my login function:
My 'password' column has this datatype: No php errors show up so the only thing I can think of is that the hash value is not formatted in the same way when it comes out of the database as when it went in, but when I echo out the values, they appear to be identical. How else can I debug this / what is wrong with my code? Thanks UPDATE: This definitely has something to do with encoding:
how do I reformat the SQL value to match the output of password_hash? Here's what I've tried:
if I do:
(PHP 5 >= 5.5.0, PHP 7, PHP 8) password_verify — Verifies that a password matches a hash Descriptionpassword_verify(string Note that password_hash() returns the algorithm, cost and salt as part of the returned hash. Therefore, all information that's needed to verify the hash is included in it. This allows the verify function to verify the hash without needing separate storage for the salt or algorithm information. This function is safe against timing attacks. Parameterspassword The user's password. hash A hash created by password_hash(). Return Values Returns ExamplesExample #1 password_verify() example
password_verify('rasmuslerdorf', $hash)) { The above example will output: See Also
What does password_ verify do in PHP?The password_verify() function can verify that given hash matches the given password. Note that the password_hash() function can return the algorithm, cost, and salt as part of a returned hash. Therefore, all information that needs to verify a hash that includes in it.
What is Password_bcrypt?PASSWORD_BCRYPT is used to create new password hashes using the CRYPT_BLOWFISH algorithm. This will always result in a hash using the "$2y$" crypt format, which is always 60 characters wide. Supported Options: salt (string) - to manually provide a salt to use when hashing the password.
What is password default in PHP?PASSWORD_DEFAULT - Use the bcrypt algorithm (default as of PHP 5.5. 0). Note that this constant is designed to change over time as new and stronger algorithms are added to PHP. For that reason, the length of the result from using this identifier can change over time.
How do I log into a hashed password?Let's start by hashing the password using password_hash() function. Open the signup. php file, and then let's create a function to hash the password. After hashing the password, we will store the hashed password in our database, so we also need to change the SQL query.
