mbed TLS 2.1.0 发布，此版本遵循 Apache 2.0 协议。此版本是首次作为 mbed OS 的 yotta module。 因为某些项目只能使用 GPL 协议，所以同时提供 Apache 协议和 GPL 协议的 mbed TLS 版本。 下载： Apache： mbedtls-2.1.0-apache.tgz mbedtls-2.1.0-apache.tgz ： SHA-1 : 13fcb4858145e972f8abaedf029ceb5c8461408e SHA-256: debd652ecf621ba3eea32c4a7eefb4c477d014d651f8ac117696e46ddaaf1b55 GPL：mbedtls-2.1.0-gpl.tgz mbedtls-2.1.0-gpl.tgz： SHA-1 : 4edf1f42871b5e2c68a86320da778cb16f173b04 SHA-256: b61b5fe6aa33ed365289478ac48f1496b97eef0fb813295e534e0c2bd435dcfc 此版本主要改进如下： 新特性 * Added support for yotta as a build system. * Primary open source license changed to Apache 2.0 license. Bug 修复 * Fix segfault in the benchmark program when benchmarking DHM. * Fix build error with CMake and pre-4.5 versions of GCC (found by Hugo Leisink). * Fix bug when parsing a ServerHello without extensions (found by David Sears). * Fix bug in CMake lists that caused libmbedcrypto.a not to be installed (found by Benoit Lecocq). * Fix bug in Makefile that caused libmbedcrypto and libmbedx509 not to be installed (found by Rawi666). * Fix compile error with armcc 5 with --gnu option. * Fix bug in Makefile that caused programs not to be installed correctly (found by robotanarchy) (#232). * Fix bug in Makefile that prevented from installing without building the tests (found by robotanarchy) (#232). * Fix missing -static-libgcc when building shared libraries for Windows with make. * Fix link error when building shared libraries for Windows with make. * Fix error when loading libmbedtls.so. * Fix bug in mbedtls_ssl_conf_default() that caused the default preset to be always used (found by dcb314) (#235) * Fix bug in mbedtls_rsa_public() and mbedtls_rsa_private() that could result trying to unlock an unlocked mutex on invalid input (found by Fredrik Axelsson) (#257) * Fix -Wshadow warnings (found by hnrkp) (#240) * Fix memory corruption on client with overlong PSK identity, around SSL_MAX_CONTENT_LEN or higher - not triggerrable remotely (found by Aleksandrs Saveljevs) (#238) * Fix unused function warning when using MBEDTLS_MDx_ALT or MBEDTLS_SHAxxx_ALT (found by Henrik) (#239) * Fix memory corruption in pkey programs (found by yankuncheng) (#210) 改进 * The PEM parser now accepts a trailing space at end of lines (#226). * It is now possible to #include a user-provided configuration file at the end of the default config.h by defining MBEDTLS_USER_CONFIG_FILE on the compiler's command line. * When verifying a certificate chain, if an intermediate certificate is trusted, no later cert is checked. (suggested by hannes-landeholm) (#220). * Prepend a "thread identifier" to debug messages (issue pointed out by Hugo Leisink) (#210). * Add mbedtls_ssl_get_max_frag_len() to query the current maximum fragment length. 更多内容请看发行说明。 PolarSSL 源码，也许是最小巧的ssl代码库。高效、便于移植和集成。尤其适合嵌入式应用。 目前 PolarSSL 已经被 ARM 公司收购，并改名为 mbed TLS。许可证也由 GPL 改为 Apache。 mbed TLS 2.1.0 发布，遵循 Apache 2.0下载地址
