===== BS2_MakePinCodeWithKey =====
[+ 2.7.1] Encryptes PIN code with the user-defined PIN encryption key.\\
The user-defined PIN encryption key must be the one set by [[BS2_SetDataEncryptKey]]. \\ 
==== Declaration ====
<code cpp>
#include "BS_API.h"

int BS2_MakePinCodeWithKey(void* context, char* plaintext, unsigned char* ciphertext, const BS2EncryptKey* key)
</code>
==== Parameter ====
  * [In] ''//context//'' : Context
  * [In] ''//plaintext//'' : Plain text needs to be encrypted 
  * [Out] ''//ciphertext//'' : Buffer to store encrypted data 
  * [In] ''//key//'' : User-defined encryption key information structure 

<WRAP indent>
<WRAP info 70%>
**NOTE**\\
ciphertext buffer size is //BS2_PIN_HASH_SIZE// 
</WRAP>
</WRAP>
==== Return Value ====
If successfully done, ''BS_SDK_SUCCESS'' will be returned. \\
