See openssl_csr_new () for more information about how to use options for a CSR. Among those options only private_key_bits, private_key_type, curve_name, and config are used for key generation. Algorithm-specific options are used if the associative array includes one of the specific keys. "rsa" key for setting RSA parameters.
May 19, 2023 · The openssl_pkey_new () function is an inbuilt function in PHP cryptography extension that is used to generate a new private/public key pair using the OpenSSL library.

The openssl_pkey_new()function will return resource identifier that has new private and public key pair.
The function openssl_pkey_new() returns a resource identifier. You can make use of openssl_pkey_get_details() function to get all the details of the key generated. The key (public/private pair) is used later with other openssl function like openssl_sign(), openssl_csr_new() - to get CSR certificate, that helps to create cryptographic digital signat...
By default openssl_pkey_new() makes use of configuration details present in openssl.cnf. But using configargs you can overwrite them.The config details are as follows:
PHP openssl_pkey_new() function returns a resource identifier if there is no error. It will return false if the key generation fails.
The key input format; unspecified by default. See openssl-format-options (1) for details. -passinarg The password source for the key input. For more information about the format of arg see openssl-passphrase-options (1). -pubin By default a private key is read from the input. With this option only the public components are read.
openssl_pkey_new () génère une nouvelle paire de clés, une privée et une publique. La partie publique en est accessible via la fonction openssl_pkey_get_public (). Note: Vous devez avoir un fichier openssl.cnf valide et installé pour que cette fonction opère correctement. Voir les notes se trouvant dans la section concernant l'installation pour plus d'informations.
openssl_pkey_new () generates a new private and public key pair. The public component of the key can be obtained using openssl_pkey_get_public (). You can finetune the key generation (such as specifying the number of bits) using configargs. See openssl_csr_new () for more information about configargs.
