openssl_password_hash — Create a password hash using OpenSSL's Argon2 implementation

Açıklama

openssl_password_hash(string $algo, string $password, array $options = []): string

Creates a password hash using OpenSSL's Argon2 implementation. This is an alternative to password_hash() that uses OpenSSL as the backend, which may offer hardware acceleration on some platforms.

This function is only available when PHP is compiled with OpenSSL support that includes Argon2 (HAVE_OPENSSL_ARGON2).

Bağımsız Değişkenler

algo

The password hashing algorithm. Supported values: "argon2id" and "argon2i".

password

The user's password.

options

An associative array of options. Supported keys:

  • memory_cost - Maximum memory (in KiB) that may be used to compute the hash
  • time_cost - Maximum amount of time it may take to compute the hash
  • threads - Number of threads to use for computing the hash

Dönen Değerler

Returns the password hash as a string.

Hatalar/İstisnalar

Throws a ValueError if algo is not one of the supported values ("argon2i" or "argon2id").

Throws an Error if the hashing operation fails for an unknown reason.
