PHP 5 >= 5.6.0, PHP 7, PHP 8
openssl_spki_new - Generate a new signed public key and challenge
Manual
openssl_spki_new(
OpenSSLAsymmetricKey$private_key,
string$challenge,
[int$digest_algo = OPENSSL_ALGO_MD5]
): string|false
OpenSSLAsymmetricKey$private_key,
string$challenge,
[int$digest_algo = OPENSSL_ALGO_MD5]
): string|false
Generates a signed public key and challenge using specified hashing algorithm
Parameters
- private_key
-
private_key should be set to a private key that was previously generated by openssl_pkey_new (or otherwise obtained from the other openssl_pkey family of functions). The corresponding public portion of the key will be used to sign the CSR.
- challenge
-
The challenge associated to associate with the SPKAC
- digest_algo
-
The digest algorithm. See openssl_get_md_method().
Return Values
Returns a signed public key and challenge string or false on failure.
Exceptions and Errors
Emits an E_WARNING level error if an unknown signature algorithm is passed via the digest_algo parameter.
