1. BaroCRYPT

 

1.1 BaroCRYPT Overview

 

The BaroCRYPT solution is a lightweight and fastest encryption algorithm based on the XXTEA (Extended Extended Tiny Encryption Algorithm), a compact and easy-to-implement block encryption algorithm using the Feistel cipher.

 

 

 

1.2 BaroCRYPT Features/Benefits

 

Based on the XXTEA (aka Corrected Block TEA) encryption algorithm, the BaroCRYPT solution is an optimal solution capable of quickly encrypting and decrypting data even under extreme constraints such as legacy hardware systems (embedded) with a minimum amount of usable RAM. Is as follows.

 

■ It is a small and easy-to-implement block encryption algorithm based on the Feistel cipher, which is small in size, fast and easy to implement.

■ It is a small-sized algorithm based on the Feistel cipher, and has high encryption strength compared to its size.

■ Although the size of the algorithm is small, it is the fastest and safest algorithm in

existence.

■ Compared to other block encryption algorithms, it is easy to implement, easy to apply to environments with large hardware specification constraints, and freely used.

■ It is a block encryption algorithm that encrypts 64 bits (8 bytes) and uses a 128 bit (16 byte)

key.

■ Corrected Block TEA (XXTEA) is a block cipher algorithm originally designed to correct the

weakness of Block TEA

■ Provides free customizing and convenience of interlocking development with various application

programs. (API integration in Java and C languages)

■ TO_ENCRYPTS (encryption) and TO_DECRYPTS (decryption) functions are provided for easy use in SQL statements.

 

※ What is a Feistel Cipher?

 

It is a repetitive block cipher in which the ciphertext is encrypted from the plaintext while repeating the same substitution and substitution. It is a cipher similar to the Data Encryption Standard (DES). The other halves do an exclusive OR (XOR) and then swap each other. Do this process in the same pattern for each permutation, but do not exchange each other in the last permutation. The subkey used during encryption is reversed during decryption.

3. Create/Use/Delete functions

 

3.1 Create function

 

MySQL's UDF (User Defined Function) is used when calling an external program written in C or C++ in MySQL or sending data.

 

It must be written in C or C++, and the operating system must support dynamic loading.

 

Copy the attached files (BaroUDF_MySQL.dll, BaroUDF_MariaDB.dll) to the directory with the following command result in mysql shell.

 

Mysql> SHOW VARIABLES LIKE 'plugin_dir';

 

To create the libBaroUDF_MySQL_info, libBaroUDF_MariaDB_info, TO_ENCRYPTS, TP_DECRYPTS functions, execute the following commands in mysql shell.

 

1) For MySQL

 

mysql> create function libBaroUDF_MySQL_info returns string soname 'BaroUDF_MySQL.dll'; mysql> create function TO_ENCRYPTS           returns string soname 'BaroUDF_MySQL.dll'; mysql> create function TO_DECRYPTS           returns string soname 'BaroUDF_MySQL.dll';

 

2) For MariaDB

 

mysql> create function libBaroUDF_MariaDB_info returns string soname 'BaroUDF_MariaDB.dll'; mysql> create function TO_ENCRYPTS             returns string soname 'BaroUDF_MariaDB.dll'; mysql> create function TO_DECRYPTS             returns string soname 'BaroUDF_MariaDB.dll';

 

 

3.2 Use function

 

To use the libBaroUDF_MySQL_info, libBaroUDF_MariaDB_info, TO_ENCRYPTS, and TP_DECRYPTS functions, execute the following commands in mysql shell.
