>Nogle biblioteker putter helt automatisk salt, algoritme og antal iterationer i hash output
det gør bla. password-hash
ref
https://www.php.net/manual/en/function.password-hash.phpThe following algorithms are currently supported:
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. Therefore, it is recommended to store the result in a database column that can expand beyond 60 characters (255 characters would be a good choice).
PASSWORD_BCRYPT - Use the CRYPT_BLOWFISH algorithm to create the hash. This will produce a standard crypt() compatible hash using the "$2y$" identifier. The result will always be a 60 character string, or FALSE on failure.
PASSWORD_ARGON2I - Use the Argon2i hashing algorithm to create the hash. This algorithm is only available if PHP has been compiled with Argon2 support.
PASSWORD_ARGON2ID - Use the Argon2id hashing algorithm to create the hash. This algorithm is only available if PHP has been compiled with Argon2 support.
Supported options for PASSWORD_BCRYPT:
salt (string) - to manually provide a salt to use when hashing the password. Note that this will override and prevent a salt from being automatically generated.
If omitted, a random salt will be generated by password_hash() for each password hashed. This is the intended mode of operation.
Warning
The salt option has been deprecated as of PHP 7.0.0. It is now preferred to simply use the salt that is generated by default.
så hvis man ikke angiver en salt bliver der automatisk generaret en random salt
