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.

非常详细的高精度碰撞检测代码，精确到三角形、边、点，优化过滑动时的碰撞检测，完全没有震动现象。代码中把三角形等元素具体成类参与计算的方法很有参考价值。 代码内含3d向量计算函数，在ogengl、d3d下均可运行。-Very detailed high-precision collision detection code, accurate to the triangle, edge, point, when optimized sliding collision detection, there is no vibration phenomenon. Code elements such as the triangle into a specific type of calculation is very involved in reference value. Code containing the 3d vector calculation function, in ogengl, d3d may run under.
