wolfssl/wolfssl

This is the Expressif Component Version of wolfSSL 5.6, Release #1 (version ^5.6.0-dev) For questions or beta test of this library, please send a message to support@wolfssl.com The [wolfSSL embedded TLS library](https://www.wolfssl.com/products/wolfssl/) is a lightweight, portable, C-language-based SSL/TLS library targeted at IoT, embedded, and RTOS environments primarily because of its size, speed, and feature set. It works seamlessly in desktop, enterprise, and cloud environments as well. wolfSSL supports industry standards up to the current [TLS 1.3](https://www.wolfssl.com/tls13) and DTLS 1.3, is up to 20 times smaller than OpenSSL, offers a simple API, an OpenSSL compatibility layer, OCSP and CRL support, is backed by the robust [wolfCrypt cryptography library](https://github.com/wolfssl/wolfssl/tree/master/wolfcrypt), and much more. The CMVP has issued FIPS 140-2 Certificates #3389 and #2425 for the wolfCrypt Module developed by wolfSSL Inc. For more information, see our [FIPS FAQ](https://www.wolfssl.com/license/fips/) or contact fips@wolfssl.com. # Getting Started Check out the Examples on the right pane of the [wolfssl component page](https://components.espressif.com/components/wolfssl/wolfssl/). Typically you need only 4 lines to run an example from scratch in the EDP-IDF environment: ``` . ~/esp/esp-idf/export.sh idf.py create-project-from-example "wolfssl/wolfssl^5.6.0-stable:wolfssl_benchmark" cd wolfssl_benchmark idf.py -b 115200 flash monitor ``` or for VisualGDB: ``` . /mnt/c/SysGCC/esp32/esp-idf/v5.0/export.sh ``` ### Espressif Component Notes Here are some ESP Registry-specific details of the wolfssl component. #### Component Name The naming convention of the build-system name of a dependency installed by the component manager is always `namespace__component`. The namespace for wolfSSL is `wolfssl`. The build-system name is thus `wolfssl__wolfssl`. We'll soon be publishing `wolfssl__wolfssh`, `wolfssl__wolfmqtt` and more. A project `cmakelists.txt` doesn't need to mention it at all when using wolfSSL as a managed component. #### Component Manager To check which version of the [Component Manager](https://docs.espressif.com/projects/idf-component-manager/en/latest/getting_started/index.html#checking-the-idf-component-manager-version) is currently available, use the command: ``` python -m idf_component_manager -h ``` The Component Manager should have been installed during the [installation of the ESP-IDF](https://docs.espressif.com/projects/esp-idf/en/latest/esp32/get-started/#installation). If your version of ESP-IDF doesnt come with the IDF Component Manager, you can [install it](https://docs.espressif.com/projects/idf-component-manager/en/latest/guides/updating_component_manager.html#installing-and-updating-the-idf-component-manager): ``` python -m pip install --upgrade idf-component-manager ``` For further details on the Espressif Component Manager, see the [idf-component-manager repo](https://github.com/espressif/idf-component-manager/). #### Contact Have a specific request or questions?

It is commonly used in standard operating environments as well because of its royalty-free pricing and excellent cross platform support. wolfSSL supports industry standards up to the current [TLS 1.3](https://www.wolfssl.com/tls13) and DTLS 1.2, is up to 20 times smaller than OpenSSL, and offers progressive ciphers such as ChaCha20, Curve25519, Blake2b and Post-Quantum TLS 1.3 groups. User benchmarking and feedback reports dramatically better performance when using wolfSSL over OpenSSL. wolfSSL is powered by the wolfCrypt cryptography library. Two versions of wolfCrypt have been FIPS 140-2 validated (Certificate #2425 and certificate #3389). FIPS 140-3 validation is in progress. For additional information, visit the [wolfCrypt FIPS FAQ](https://www.wolfssl.com/license/fips/) or contact fips@wolfssl.com. ## Why Choose wolfSSL? There are many reasons to choose wolfSSL as your embedded, desktop, mobile, or enterprise SSL/TLS solution. Some of the top reasons include size (typical footprint sizes range from 20-100 kB), support for the newest standards (SSL 3.0, TLS 1.0, TLS 1.1, TLS 1.2, TLS 1.3, DTLS 1.0, and DTLS 1.2), current and progressive cipher support (including stream ciphers), multi-platform, royalty free, and an OpenSSL compatibility API to ease porting into existing applications which have previously used the OpenSSL package. For a complete feature list, see [Chapter 4](https://www.wolfssl.com/docs/wolfssl-manual/ch4/) of the wolfSSL manual. ## Notes, Please Read ### Note 1 wolfSSL as of 3.6.6 no longer enables SSLv3 by default. wolfSSL also no longer supports static key cipher suites with PSK, RSA, or ECDH. This means if you plan to use TLS cipher suites you must enable DH (DH is on by default), or enable ECC (ECC is on by default), or you must enable static key cipher suites with one or more of the following defines: ``` WOLFSSL_STATIC_DH WOLFSSL_STATIC_RSA WOLFSSL_STATIC_PSK ``` Though static key cipher suites are deprecated and will be removed from future versions of TLS. They also lower your security by removing PFS. When compiling `ssl.c`, wolfSSL will now issue a compiler error if no cipher suites are available. You can remove this error by defining `WOLFSSL_ALLOW_NO_SUITES` in the event that you desire that, i.e., you're not using TLS cipher suites. ### Note 2 wolfSSL takes a different approach to certificate verification than OpenSSL does. The default policy for the client is to verify the server, this means that if you don't load CAs to verify the server you'll get a connect error, no signer error to confirm failure (-188). If you want to mimic OpenSSL behavior of having `SSL_connect` succeed even if verifying the server fails and reducing security you can do this by calling: ```c wolfSSL_CTX_set_verify(ctx, WOLFSSL_VERIFY_NONE, NULL); ``` before calling `wolfSSL_new();`. Though it's not recommended. ### Note 3 The enum values SHA, SHA256, SHA384, SHA512 are no longer available when wolfSSL is built with `--enable-opensslextra` (`OPENSSL_EXTRA`) or with the macro `NO_OLD_SHA_NAMES`. These names get mapped to the OpenSSL API for a single call hash function. Instead the name `WC_SHA`, `WC_SHA256`, `WC_SHA384` and `WC_SHA512` should be used for the enum name. # wolfSSL Release 5.6.0 (Mar 24, 2023) Release 5.6.0 has been developed according to wolfSSL's development and QA process (see link below) and successfully passed the quality criteria. https://www.wolfssl.com/about/wolfssl-software-development-process-quality-assurance NOTE: * --enable-heapmath is being deprecated and will be removed by 2024 * This release makes ASN Template the default with ./configure, the previous ASN parsing can be built with --enable-asn=original Release 5.6.0 of wolfSSL embedded TLS has bug fixes and new features including: ##

# wolfSSL Benchmark Example This is the ESP32 Version of the [wolfSSL wolfcrypt Benchmark Application](https://github.com/wolfSSL/wolfssl/tree/master/wolfcrypt/benchmark).  ## VisualGDB Open the VisualGDB Visual Studio Project file in the VisualGDB directory and click the "Start" button. No wolfSSL setup is needed. You may need to adjust your specific COM port. The default is `COM20`. ## ESP-IDF Commandline 1. `idf.py menuconfig` to configure the program. 1-1. Example Configuration -> BENCH_ARG : argument that you want to use. Default is "-lng 0" The list of argument can be find in help. When you want to run the benchmark program 1. `idf.py -p <PORT> flash` to compile and load the firmware 2. `idf.py monitor` to see the message See the README.md file in the upper level 'examples' directory for more information about examples. ## Performance Reminder than when building on WSL in `/mnt/c` there will be a noticeable performance degradation at compile time. Using `~/` will be faster at the cost of shared filesystems. Example build on WSL: ``` Optionally install wolfSSL component # cd /mnt/c/workspace/wolfssl/IDE/Espressif/ESP-IDF ./setup.sh cd /mnt/c/workspace/wolfssl/IDE/Espressif/ESP-IDF/examples/wolfssl_benchmark # Pick ESP-IDF install directory, this one for v4.4.2 in VisualGDB . /mnt/c/SysGCC/esp32/esp-idf/v4.4.2/export.sh idf.py build flash -p /dev/ttyS20 -b 115200 monitor ``` ## Example Output Note the default wolfSSL `user_settings.h` is configured by default to be the most compatible across the widest ranges of targets. Contact wolfSSL at support@wolfssl.com for help in optimizing for your particular application, or see the [docs](https://www.wolfssl.com/documentation/manuals/wolfssl/index.html). Compiled and flashed with `idf.py build flash -p /dev/ttyS7 -b 115200 monitor`: ``` --- idf_monitor on /dev/ttyS7 115200 --- --- Quit: Ctrl+] | Menu: Ctrl+T | Help: Ctrl+T followed by Ctrl+H --- (377) cpu_start: Starting scheduler ets Jun 8 2016 00:22:57 rst:0x1 (POWERON_RESET),boot:0x13 (SPI_FAST_FLASH_BOOT) configsip: 0, SPIWP:0xee clk_drv:0x00,q_drv:0x00,d_drv:0x00,cs0_drv:0x00,hd_drv:0x00,wp_drv:0x00 mode:DIO, clock div:2 load:0x3fff0030,len:6664 load:0x40078000,len:14848 load:0x40080400,len:3792 0x40080400: _init at ??:? entry 0x40080694 I (27) boot: ESP-IDF v4.4.2-dirty 2nd stage bootloader I (27) boot: compile time 13:41:41 I (27) boot: chip revision: 1 I (30) boot_comm: chip revision: 1, min. bootloader chip revision: 0 I (37) boot.esp32: SPI Speed : 40MHz I (42) boot.esp32: SPI Mode : DIO I (46) boot.esp32: SPI Flash Size : 2MB I (51) boot: Enabling RNG early entropy source...

Ensure no other build process is using the same files in Windows, WSL, Visual Studio, VSCode, etc. Example message: ``` -- Building ESP-IDF components for target esp32 CMake Error at /mnt/c/SysGCC/esp32/esp-idf/v4.4.2/tools/cmake/component.cmake:131 (file): file failed to open for writing (Permission denied): /mnt/c/workspace-pr/wolfssl/IDE/Espressif/ESP-IDF/examples/wolfssl_test/build/bootloader/component_properties.temp.cmake ``` ### user_settings.h: No such file or directory Ensure wolfSSL is installed in the ESP-IDF or local project `components` directory. Example message: ``` esp-idf/main/CMakeFiles/__idf_main.dir/main.c.obj -c ../main/main.c ../main/main.c:27:10: fatal error: user_settings.h: No such file or directory #include <user_settings.h> ^~~~~~~~~~~~~~~~~ compilation terminated. ``` A 'clean` may be needed after freshly installing a new component: ``` idf.py clean build flash -p /dev/ttyS7 -b 115200 monitor ``` ### ESP Component Registry This tag is used to include this file in the ESP Component Registry: __ESP_COMPONENT_SOURCE__
