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.

利用边界追踪法对图像进行轮廓提取，此函数文件得到的是边界点对应位置索引矩阵-The use of boundary-tracing method of image contour extraction, this function is to document the location of boundary points corresponding to the index matrix

实现从CAD环境下的地理坐标元素四参数转换，包括点，线，文字，面，块等-AUTOCAD

1.鼠标交互式绘制三次bezier曲线 2.Bezier曲线的C0,C1,C2连续拼接, 3.交互式操作(绘制好后可以鼠标拖动控制点,bezier曲线实时更新)-1. Mouse interactive rendering Bezier curves 2.Bezier three curves C0, C1, C2 for splicing, 3. Interactive operations (drawing good can drag the control point the mouse, bezier curves of real-time updates)
