openssl_private_decrypt() decrypts `data` that was previous encrypted via openssl_public_encrypt() and stores the result into `decrypted`. `key` must be the private key corresponding that was used to encrypt the data. `padding` defaults to OPENSSL_PKCS1_PADDING, but can also be one of OPENSSL_SSLV23_PADDING, OPENSSL_PKCS1_OAEP_PADDING, OPENSSL_NO_PADDING.

Returns `TRUE` on success or `FALSE` on failure.

You can use this function e.g. to decrypt data which were supposed only to you.
