![]() Ephemeral key generation can be requested from any of the ffdheXYZ(dh) variants' common ->set_secret() by passing it an (encoded) struct dh with the key parameter being unset, i.e. with ->key_size == 0. As the whole purpose of the ffdheXYZ(dh) templates is to fill in the group parameters as appropriate, they expect ->p and ->g to be unset in any input struct dh as well. This means that a user would have to encode an all-zeroes struct dh instance via crypto_dh_encode_key() when requesting ephemeral key generation from a ffdheXYZ(dh) instance, which is kind of pointless. Make dh_safe_prime_set_secret() to decode a struct dh from the supplied buffer only if the latter is non-NULL and initialize it with all zeroes otherwise. That is, it is now possible to call crypto_kpp_set_secret(tfm, NULL, 0); on any ffdheXYZ(dh) tfm for requesting ephemeral key generation.

Linux kernel ============ There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. The formatted documentation can also be read online at: https://www.kernel.org/doc/html/latest/ There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
