![]() ![]() The password_verify() function takes a plain password and the hashed string as its two arguments. Remember that you store the hashes in a database, but it’s the plain password that you get when a user logs in. Now that you have seen how to generate hashes with the new API, let’s see how to verify a password. If PHP later decides to implement a more powerful hashing algorithm your code can take advantage of it. In this way, you are always up-to-date with new security measures. ![]() $hash = password_hash($password, PASSWORD_DEFAULT, $options) custom_function_for_salt(), //write your own code to generate a suitable salt Some developers then use a weak salt and weak algorithm for generating a hash instead, for example: It is important to note, however, that hashing passwords only protects them from being compromised in your data store, but does not necessarily protect them from being intercepted by malicious code injected into your application itself.Īlthough the crypt() function is secure, it’s considered by many to be too complicated and prone to programmer error. Without hashing, any passwords that are stored in yourĪpplication's database can be stolen if the database is compromised, and then immediately used to compromise not only your application, but also the accounts of your users on other services, if they do not use unique passwords.īy applying a hashing algorithm to your user's passwords before storing them in your database, you make it implausible for any attacker to determine the original password, while still being able to compare the resulting hash to the original password in the future. Password hashing is one of the most basic security considerations that must be made when designing any application that accepts passwords from users. Password_get_info() – returns the name of the hashing algorithm and various options used while hashing. Password_needs_rehash() – used when a password needs to be rehashed. Password_verify() – used to verify a password against its hash. Password_hash() – used to hash the password. The new password hashing API exposes four simple functions: ![]()
