后续包括自签证书的生成、openssl服务端服务器测试环境的搭建等功能,记录在了另一篇文章里,有兴趣的欢迎查看指正。 (抱怨一句:测试的加密套件使用的 TLS_RSA_WITH_AES_256_CBC_SHA256,结果客户的设置需要使用TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384,又去了解怎么配置、怎么测试,来回的折腾…) 文章链接:使用opens...

Hello ! NXP implement own pair of APIs mbedtls_gcm_crypt_and_tag/mbedtls_gcm_auth_decrypt what is LTC accelerated. But it is not so clear if context
This occurs because NXP added MBEDTLS_AES_GCM_STARTS_ALT, MBEDTLS_AES_GCM_UPDATE_ALT, etc to define alternate functions for the standard mbedTLS GCM functions, but did not exclude the static functions that the standard functions utilize. I've attached the original ...
GCM modules no longer depend on MBEDTLS_CIPHER_C. Also, MBEDTLS_PSA_CRYPTO can now be enabled without MBEDTLS_CIPHER_C if all unauthenticated (non-AEAD) ciphers are disabled, or if they're all fully provided by drivers. See docs/driver-only-builds.md for full ...
int mbedtls_cipher_update_ad(mbedtls_cipher_context_t*ctx, const unsigned char *ad, size_tad_len ) Add additional data (for AEAD ciphers). Currently only supported with GCM. Must be called exactly once, aftermbedtls_cipher_reset().
