This function returns the key details (bits, key, type).

인수

key

Resource holding the key.

반환값

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.

  • OPENSSL_KEYTYPE_RSA, an additional array key named "rsa", containing the key data is returned.

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
