Since 2017, NIST recommends using a secret input when hashing memorized secrets such as passwords. The only exception to this is in anĮmergency when a critical security flaw is found in the current

The default should only change in a full release (7.3.0, 8.0.0, etc)Īnd not in a revision release. In 7.6.0, it would also be eligible for default at 7.7.0. In 7.5.5, it would not be eligible for default until 7.7 (since 7.6 So if, for example, a new algorithm is added Updates to supported algorithms by this function (or changes to the default one) must followĪny new algorithm must be in core for at least 1 full release of PHP The script in the above example will help you choose a good cost value for your hardware. So that execution of the function takes less than 100 milliseconds on interactive systems. It is recommended that you test this function on your servers, and adjust the cost parameter It will create a secure salt automatically for you if you doĪs noted above, providing the salt option in PHP 7.0 It is strongly recommended that you do not generate your own salt for thisįunction.

If omitted, a random salt will be generated by password_hash() forĮach password hashed. Note that this will override and prevent a salt from being automatically generated. Salt ( string) - to manually provide a salt to use when hashing the password. PASSWORD_ARGON2ID - Use the Argon2id hashing algorithm to create the hash.This algorithm is only available if PHP has been compiled with Argon2 support. PASSWORD_ARGON2I - Use the Argon2i hashing algorithm to create the hash.The result will always be a 60 character string, or false on failure. This will produce a standard crypt() compatible hash using

PASSWORD_BCRYPT - Use the CRYPT_BLOWFISH algorithm toĬreate the hash.

Therefore, it is recommended to store the result in a database column that can expandīeyond 60 characters (255 characters would be a good choice). For that reason, the length of the result from using this identifier can change over Note that this constant is designed to change over time as new and stronger algorithms are added

PASSWORD_DEFAULT - Use the bcrypt algorithm (default as of PHP 5.5.0).

The following algorithms are currently supported: Password_hash() creates a new password hash using a strong one-way hashing

Password_hash( string $password, string| int| null $algo, array $options = ): string
