(PHP 4 >= 4.0.6, PHP 5)

openssl_public_encrypt -- Encrypts data with public key

## Description

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

openssl_public_encrypt() encrypts data with public key and stores the result into crypted. Encrypted data can be decrypted via openssl_private_decrypt(). padding defaults to `OPENSSL_PKCS1_PADDING`, but can also be one of `OPENSSL_SSLV23_PADDING`, `OPENSSL_PKCS1_OAEP_PADDING`, `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 encrypt message which can be then read only by owner of the private key. It can be also used to store secure data in database.
