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

openssl_pkey_get_details — Returns an array with the key details
Descrierea
openssl_pkey_get_details
( resource
$key
) : arrayThis function returns the key details (bits, key, type).
Parametri

key -
Resource holding the key.
Valorile întoarse
Returns an array with the key details in success or false in 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.
