How to get mbed TLS
mbed TLS is primarily available under the Apache 2.0 open source license. A GPL-licensed version is also available if you have different needs.
Open Source / Apache 2.0
All the current versions of the mbed TLS library are distributed under the Apache 2.0 license and available from our Download area. In addition there are packaged versions of the mbed TLS library that are distributed with the GNU Public License Version 2.0 (GPL v2.0).
The Apache-licensed and GPL-licensed versions of mbed TLS are identical in source code (with the exception of the license headers at the top of files).
We plan to keep both licensed versions around.
