## TLS Support
|
|
|
|
At the moment there are two different options for TLS support.
|
|
|
|
* mbedtls 2.28 supports TLS version 1.2, 1.1 and older versions of TLS
|
|
* mbedtls 3.6 supports TLS versions 1.2 and 1.3
|
|
|
|
### mbedtls 2.28
|
|
|
|
For TLS support with mbedtls 2.28 download the source tarball of version 2.28.x and extract here in the subfolder (Version 2.28.10 https://github.com/Mbed-TLS/mbedtls/releases/download/mbedtls-2.28.10/mbedtls-2.28.10.tar.bz2)
|
|
|
|
On a Linux command line enter the following commands in this directory:
|
|
|
|
wget https://github.com/Mbed-TLS/mbedtls/releases/download/mbedtls-2.28.10/mbedtls-2.28.10.tar.bz2
|
|
tar xfj mbedtls-2.28.10.tar.bz2
|
|
|
|
To allow session resumption within an ongoing TLS connection (required by IEC 62351-3:2023) a patch (mbedtls_2.28_ssl_srv.c.patch) has to be applied to the mbedtls source code:
|
|
|
|
patch mbedtls-2.28.10/library/ssl_srv.c mbedtls_2.28_ssl_srv.c.patch
|
|
|
|
When running cmake the build system will automatically find the mbedtls source code and includes it into the library build.
|
|
|
|
When using make the make command has to be invoked with the WITH_MBEDTLS=1 parameter
|
|
|
|
make WITH_MBEDTLS=1
|
|
|
|
### mbedtls 3.6
|
|
|
|
For TLS support with mbedtls 3.6 download the source tarball of version 3.6.x and extract here in the subfolder (Version 3.6.2 https://github.com/Mbed-TLS/mbedtls/releases/download/mbedtls-3.6.2/mbedtls-3.6.2.tar.bz2)
|
|
|
|
On a Linux command line enter the following commands in this directory:
|
|
|
|
wget https://github.com/Mbed-TLS/mbedtls/releases/download/mbedtls-3.6.2/mbedtls-3.6.2.tar.bz2
|
|
tar xfj mbedtls-3.6.2.tar.bz2
|
|
|
|
When running cmake the build system will automatically find the mbedtls source code and includes it into the library build.
|
|
|
|
When using make the make command has to be invoked with the WITH_MBEDTLS3=1 parameter
|
|
|
|
make WITH_MBEDTLS3=1
|
