## This is a staging experimental version! The name of this components is `mywolfssl` to distinguish it from the release version. This is wolfSSL version 5.7.4-Preview4, Published as an Espressif Managed Component When testing staging components, be sure to set `IDF_COMPONENT_REGISTRY_URL`: ``` export IDF_COMPONENT_REGISTRY_URL=https://components-staging.espressif.com ``` Set the value when not testing: ``` export IDF_COMPONENT_REGISTRY_URL=https://components.espressif.com ``` To use this STAGING instance of wolfSSL in another project, use a conditional component name `${WOLFSSL_COMPONENT_NAME}"` and add this section to the respective CMakeLists.txt file: ``` if( "$ENV{IDF_COMPONENT_REGISTRY_URL}" STREQUAL "https://components-staging.espressif.com" ) # When set to a specific value, IDF_COMPONENT_REGISTRY_URL indicates the component is used for testing / preview if( ( NOT ("${managed_components}" STREQUAL "" )) OR ( NOT ("${component_manager_interface_version}" STREQUAL "" )) OR ( ("${IDF_COMPONENT_MANAGER}" STREQUAL "1" )) ) # Alternate naming for staging component message(STATUS "*********************************************************************************") message(STATUS "*********************************************************************************") message(STATUS "* *") message(STATUS "* NOTICE: Using wolfSSL preview test library called mywolfssl from *") message(STATUS "* *") message(STATUS "* IDF_COMPONENT_REGISTRY_URL = https://components-staging.espressif.com *") message(STATUS "* *") message(STATUS "*********************************************************************************") message(STATUS "*********************************************************************************") set(WOLFSSL_COMPONENT_NAME "mywolfssl") else() # Detected IDF_COMPONENT_REGISTRY_URL as staging, but could not confirm component manager message(STATUS "*********************************************************************************") message(STATUS "*********************************************************************************") message(STATUS "* *") message(STATUS "* WARNING: could not detect component manager, using wolfSSL component wolfssl *") message(STATUS "* *") message(STATUS "* IDF_COMPONENT_REGISTRY_URL = https://components-staging.espressif.com *") message(STATUS "* *") message(STATUS "*********************************************************************************") message(STATUS "*********************************************************************************") set(WOLFSSL_COMPONENT_NAME "wolfssl") endif() else() set(WOLFSSL_COMPONENT_NAME "wolfssl") endif() # Set the conditional name of the COMPONENT_REQUIRES value: set(COMPONENT_REQUIRES lwip "${WOLFSSL_COMPONENT_NAME}") message(STATUS "WOLFSSL_COMPONENT_NAME= ${WOLFSSL_COMPONENT_NAME}") # or then registering the component, use the variable name: idf_component_register( SRCS "main.c" REQUIRES esp_wifi esp_partition ${WOLFSSL_COMPONENT_NAME}" ) ``` You can also use your own conditional logic. As seen above, the release version is called `wolfssl` and the staging version is called `mywolfssl`. ** End of staging prepend notes. ** # Release README  This is wolfSSL version 5.7.4-Preview4, Published as an Espressif Managed Component For questions or beta test of this library, please send a message to support@wolfssl.com For details on how wolfSSL is published to the ESP Component Registry, see the [INSTALL.md](https://github.com/wolfssl/wolfssl/tree/master/IDE/Espressif/component-manager/INSTALL.md) file. See the [wolfSSL Manual](https://www.wolfssl.com/documentation/manuals/wolfssl/index.html). 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: ```bash . ~/esp/esp-idf/export.sh idf.py create-project-from-example "gojimmypi/mywolfssl^5.7.4-Preview4" cd wolfssl_benchmark idf.py -b 115200 flash monitor ``` or for VisualGDB: ```bash . /mnt/c/SysGCC/esp32/esp-idf/v5.1/export.sh idf.py create-project-from-example "gojimmypi/mywolfssl^5.7.4-Preview4" cd wolfssl_benchmark idf.py -b 115200 flash monitor ``` ### 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 doesn't 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 1.3, 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, DTLS 1.2, and DTLS 1.3), 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 5.7.4 (Oct 24, 2024) Release 5.7.4 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 end of 2024 PR stands for Pull Request, and PR <NUMBER> references a GitHub pull request number where the code change was added. ## Vulnerabilities * [Low] When the OpenSSL compatibility layer is enabled, certificate verification behaved differently in wolfSSL than OpenSSL, in the X509_STORE_add_cert() and X509_STORE_load_locations() implementations. Previously, in cases where an application explicitly loaded an intermediate certificate, wolfSSL was verifying only up to that intermediate certificate, rather than verifying up to the root CA. This only affects use cases where the API is called directly, and does not affect TLS connections. Users that call the API X509_STORE_add_cert() or X509_STORE_load_locations() directly in their applications are recommended to update the version of wolfSSL used or to have additional sanity checks on certificates loaded into the X509_STORE when verifying a certificate. (https://github.com/wolfSSL/wolfssl/pull/8087) ## PQC TLS Experimental Build Fix * When using TLS with post quantum algorithms enabled, the connection uses a smaller EC curve than agreed on. Users building with --enable-experimental and enabling PQC cipher suites with TLS connections are recommended to update the version of wolfSSL used. Thanks to Daniel Correa for the report.
