License

We appreciate material and works produced for the community. Documentation, patches, and sample programs help ensure the library is reliable and easy to use. To ensure the most benefit to the project and community, contributions to this wiki must be either:

1. existing material copied from a public domain source
2. original content created by you and released under the current OpenSSL license (and any future version of it that the OpenSSL project may adopt)
3. existing content already released under the current or future OpenSSL license.

The current OpenSSL licence is an "Apache style" license. We are moving to the Apache license soon; see our blog posts.

Source Code Patches

If you contribute patches for the library source code, then the OpenSSL project will use the OpenSSL license. Not all patches will be accepted or Incorporated, and there are a variety of reasons why such changes may not be accepted and utilized by the project (not all of them readily apparent). See Contributions for a discussion of patches and potential concerns.

Sample Programs

If you contribute original sample programs for using the library, then the OpenSSL project will use the OpenSSL license. You should place the following text at the top of the source files:

Contents licensed under the terms of the OpenSSL license: https://www.openssl.org/source/license.html

You must also sign a CLA.

Man Page Documentation

If you contribute original documentation for the source code, then the OpenSSL project will use the OpenSSL license. You will not need to do anything to ensure your changes are suitable for use by by the project. As with source code there are a variety of reasons why documentation may not be accepted and utilized by the project, not all of them readily apparent [note: the topic of contributions deserves a separate discussion];
