功能和界面全部模仿于Windows自带的画图板，界面如截图。功能主要有： 手绘线、简单图形、文字输入、图块拖放、重复撤销、画面缩放、打开保存图片文件，另外为了直接从数据库或者XML中存取图片，另外还提供了从Base64编码存取图片的接口，其他还实现了和画图板同样效果的工具箱及颜料盒。 -Features and interfaces in Windows, bringing all to imitate the drawing board, interface, such as screenshots. The main features include: hand-drawn lines, simple graphics, text input, drag and drop block, repeated withdrawal, screen zoom, open the saved image file, and directly from the database in order to access images or XML, in addition to the provision of deposit from the Base64 encoding picture of the interface from the other have also achieved the same effect and drawing board of the toolbox and the color cartridge.

STM32 Cryptographic Library Introduction This manual describes the API of the STM32 cryptographic library (STM32-CRYP-LIB) that supports the following cryptographic algorithms:  AES-128, AES-192, AES-256 bits. Supported modes are: – ECB (Electronic Codebook Mode) – CBC (Cipher-Block Chaining) with support for ciphertext stealing – CTR (CounTer Mode) – CCM (Counter with CBC-MAC) – GCM (Galois Counter Mode) – CMAC – KEY WRAP  ARC4  DES, TripleDES. Supported modes are: – ECB (Electronic Codebook Mode) – CBC (Cipher-Block Chaining)  HASH functions with HMAC support: – MD5 – SHA-1 – SHA-224 – SHA-256  Random engine based on DRBG-AES-128  RSA signature functions with PKCS#1v1.5  ECC (Elliptic Curve Cryptography): – Key generation – Scalar multiplication (the base for ECDH) – ECDSA These cryptographic algorithms can run in the series STM32F1, STM32 L1, STM32F2, STM32F4, STM32F0 and STM32F3 with hardware enhancement accelerators.

数字水印处理系统主要由水印嵌入和水印检测两个过程。（1）水印嵌入过程为：数字水印（X）、原图像（I）和密钥/公钥（K）通过数字水印嵌入算法形成嵌入水印后的图像（I*）。 （2）水印检测过程为：数字水印（X）、水印图像（I*）和密钥/公钥（K）通过数字水印检测算法检测出数字水印或有无水印。该程序调试已通过！-Digital watermarking system mainly consists of watermark embedding and watermark detection of the two processes. (1) The watermark embedding process as follows: Digital watermarking (X), the original image (I) and key/public key (K) by digital watermark embedding algorithm to form watermarked image (I*). (2) The watermark detection process is as follows: Digital watermarking (X), the watermark image (I*) and key/public key (K) by digital watermark detection algorithm to detect whether the digital watermark or watermark. The program debugging has passed!
