Encrypt using public key, decrypt using private key. Use this to store stuff in your database: Unless someone has your private key, the database contents are useless. Also, use this for sending to a specific individual: Get their public key, encrypt the message, only they can use their private key to decode it. <?php echo "Source: $source"; $fp=fopen("/path/to/certificate.crt","r"); $pub_key=fread($fp,8192); fclose($fp); openssl_get_publickey($pub_key); /* * NOTE: Here you use the $pub_key value (converted, I guess) */ openssl_public_encrypt($source,$crypttext,$pub_key); echo "String crypted: $crypttext"; $fp=fopen("/path/to/private.key","r"); $priv_key=fread($fp,8192); fclose($fp); // $passphrase is required if your key is encoded (suggested) $res = openssl_get_privatekey($priv_key,$passphrase); /* * NOTE: Here you use the returned resource value */ openssl_private_decrypt($crypttext,$newsource,$res); echo "String decrypt : $newsource"; ?> |
