These are the missing descriptions for RSA elements:
n - modulus
e - publicExponent
d - privateExponent
p - prime1
q - prime2
dmp1 - exponent1, d mod (p-1)
dmq1 - exponent2, d mod (q-1)
iqmp - coefficient, (inverse of q) mod p

(PHP 5 >= 5.2.0, PHP 7, PHP 8)
openssl_pkey_get_details — Returns an array with the key details
Descrizione
This function returns the key details (bits, key, type).
Elenco dei parametri
-
key -
Resource holding the key.
Valori restituiti
Returns an array with the key details on success or false on failure.
Returned array has indexes bits (number of bits),
key (string representation of the public key) and
type (type of the key which is one of
OPENSSL_KEYTYPE_RSA,
OPENSSL_KEYTYPE_DSA,
OPENSSL_KEYTYPE_DH,
OPENSSL_KEYTYPE_EC or -1 meaning unknown).
Depending on the key type used, additional details may be returned. Note that some elements may not always be available.
