What is the most used method for hashing password in php?
(PHP 5 >= 5.5.0, PHP 7, PHP 8) Show password_hash — Creates a password hash Descriptionpassword_hash(string The following algorithms are currently supported:
Supported options for
Supported options for
Parameterspassword The user's password. Caution Using the algo A password algorithm constant denoting the algorithm to use when hashing the password. options An associative array containing options. See the password algorithm constants for documentation on the supported options for each algorithm. If omitted, a random salt will be created and the default cost will be used. Return ValuesReturns the hashed password. The used algorithm, cost and salt are returned as part of the hash. Therefore, all information that's needed to verify the hash is included in it. This allows the password_verify() function to verify the hash without needing separate storage for the salt or algorithm information.

Which hashing method is used for the password?There are many hashing algorithms that people have used to hash passwords. Two of the most common hashing algorithms you may have come across are MD5 and the SHA-* family of algorithms (SHA-1, SHA-2, SHA-3), but there are several reasons not to use these. For starters, they are extremely fast.
Is PHP password hash secure?PHP provides a native password hashing API that safely handles both hashing and verifying passwords in a secure manner. Another option is the crypt() function, which supports several hashing algorithms.
What hashing algorithm does PHP use?PHP has a total of 46 registered hashing algorithms among which “sha1”, “sha256”, “md5”, “haval160, 4” are the most popular ones. $string: This parameter expects the string to be hashed. $getRawOutput: This optional parameter expects a boolean value, on TRUE the function returns the hash in a raw binary format.
What is the most secure password hashing algorithm?To the time of writing, SHA-256 is still the most secure hashing algorithm out there. It has never been reverse engineered and is used by many software organizations and institutions, including the U.S. government, to protect sensitive information.
