openssl_open opens (decrypts)
data using the private key associated with
the key identifier private_key and the envelope key
encrypted_key, and fills
output with the decrypted data.
The envelope key is generated when the
data are sealed and can only be used by one specific private key. See
openssl_seal for more information.
