替代ATECC608A的完美兼容加密芯片

 最近发现了一款ATECC608A的完美兼容替代加密芯片，型号是MODSEMI的MOD8ID，真正做到了P2P兼容，感人的是，不需要改变主机端原有的Cryptolib库，甚至无需更改任何代码和硬件即可完美适配。

ECCDSA的产生密钥对签名，验签，SecureBOOT，TLS等接口功能都很完美，硬件防护也做得非常到位。不仅如此，也向下兼容了ATECC508系列，同时具备国密安全等功能。

支持DFN8小封装和SOP8。

/* [0] init: I2C通信连接、测试（使用MOD8ID通信调试，I2C驱动移植请参考ecc_i2c.c） */status = mse_init(&cfg_mod8_i2c);if (status != MSE_SUCCESS){printf(" mse_init() failed with ret=0x%08d\n", status);goto exit;}printf(" init OK.\n");/* [1] Load configuration:加载配置并锁定配置区（仅执行一次，注意：锁定后无法解锁） */status = app_load_configuration();if (status != MSE_SUCCESS){printf(" APP - Load configuration failed\n");goto exit;}printf(" Load configuration OK.\n");/* [2] Write Slot Data:生成密钥、写入密钥及应用配套数据，锁定数据区（锁定后无法解锁），前置条件：[1] */status = app_write_key();if (status != MSE_SUCCESS){printf(" APP - Write key failed\n");goto exit;}printf(" Write key OK.\n");/* [3] Sign_Verify: 签名、验签、加解密等应用，前置条件[2] */status = app_sign_verify();if (status != MSE_SUCCESS){printf(" APP - Sign_Verify failed\n");goto exit;}printf(" Sign_Verify OK.\n");/* [4] HMAC: 前置条件[2] */status = app_hmac();if (status != MSE_SUCCESS){printf(" APP - HMAC failed\n");goto exit;}printf(" HMAC OK.\n");
