openssl_private_encrypt -- Encrypts data with private key

## Description

bool openssl_private_encrypt ( string data, string &crypted, mixed key [, int padding] )

openssl_private_encrypt() encrypts data with private key and stores the result into crypted. Encrypted data can be decrypted via openssl_public_decrypt(). padding defaults to `OPENSSL_PKCS1_PADDING`, but can also be `OPENSSL_NO_PADDING`.

如果成功则返回 `TRUE`，失败则返回 `FALSE`。

This function can be used e.g. to sign data (or its hash) to prove that it is not written by someone else.
