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.
Parameters
- data
-
- output
-
If the call is successful the opened data is returned in this parameter.
- encrypted_key
-
- private_key
-
- cipher_algo
-
The cipher method.
Caution:
The default value ('RC4') is considered insecure. It is strongly recommended to explicitly specify a secure cipher method.
- iv
-
The initialization vector.
Return Values
Returns true on success or false on failure.
