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...

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 ...
But if block wise encryption in use, API chain 1) mbedtls_gcm_starts 2) mbedtls_gcm_update 3) mbedtls_gcm_finish must be used. And those APIs are not HW accelerated and actual performance is 10x less if mbedtls_gcm_crypt_and_tag/mbedtls_gcm_auth_decry...

Fix a bug in mbedtls_gcm_starts() when the bit length of the iv exceeds 2^32. Fixes #4884. Fix an uninitialized variable warning in test_suite_ssl.function with GCC version 11. Fix the build when no SHA2 module is included. Fixes #4930. Fix the build when only the bignum module ...
The GCM multipart interface has changed as described in“GCM multipart interface: application changes”. The consequences for an alternative implementation of GCM (MBEDTLS_GCM_ALT) are as follows: mbedtls_gcm_starts()now only sets the mode and the nonce (IV). The new functionmbedtls_gcm_update...
