* 25519: remove unused const, safeguard against unreduced scalars No behavior change, but it makes the existing code better match the forthcoming code for other curves. Rename nonAdjacentForm() to slide(), remove an unneeded and confusing constant, and do a reduction in slide() if 257 bits would be required. Note that in all the high-level functions, the top bit is always cleared, so the reduction is never necessary. But since the low-level functions are public, the check is a safe thing to have. * 25519: make identityElement public, deprecate neutralElement Also fix a few comments by the way.
A general-purpose programming language and toolchain for maintaining robust, optimal, and reusable software.

The ultimate goal of the Zig project is to serve users. As a first-order effect, this means users of the compiler, helping programmers to write better software. Even more important, however, are the end-users.
Zig is intended to be used to help end-users accomplish their goals. Zig should be used to empower end-users, never to exploit them financially, or to limit their freedom to interact with hardware or software in any way.
However, such problems are best solved with social norms, not with software licenses. Any attempt to complicate the software license of Zig would risk compromising the value Zig provides.
Therefore, Zig is available under the MIT (Expat) License, and comes with a humble request: use it to make software better serve the needs of end-users.
This project redistributes code from other projects, some of which have other licenses besides MIT. Such licenses are generally similar to the MIT license for practical purposes. See the subdirectories and files inside lib/ for more details.
