We already have a LICENSE file that covers the Zig Standard Library. We
no longer need to remind everyone that the license is MIT in every single
file.
Previously this was introduced to clarify the situation for a fork of
Zig that made Zig's LICENSE file harder to find, and replaced it with
their own license that required annual payments to their company.
However that fork now appears to be dead. So there is no need to
reinforce the copyright notice in every single file.
- use `PascalCase` for all types. So, AES256GCM is now Aes256Gcm.
- consistently use `_length` instead of mixing `_size` and `_length` for the
constants we expose
- Use `minimum_key_length` when it represents an actual minimum length.
Otherwise, use `key_length`.
- Require output buffers (for ciphertexts, macs, hashes) to be of the right
size, not at least of that size in some functions, and the exact size elsewhere.
- Use a `_bits` suffix instead of `_length` when a size is represented as a
number of bits to avoid confusion.
- Functions returning a constant-sized slice are now defined as a slice instead
of a pointer + a runtime assertion. This is the case for most hash functions.
- Use `camelCase` for all functions instead of `snake_case`.
No functional changes, but these are breaking API changes.
* Reorganize crypto/aes in order to separate parameters, implementations and
modes.
* Add a zero-cost abstraction over the internal representation of a block,
so that blocks can be kept in vector registers in optimized implementations.
* Add architecture-independent aesenc/aesdec/aesenclast/aesdeclast operations,
so that any AES-based primitive can be implemented, including these that don't
use the original key schedule (AES-PRF, AEGIS, MeowHash...)
* Add support for parallelization/wide blocks to take advantage of hardware
implementations.
* Align T-tables to cache lines in the software implementations to slightly
reduce side channels.
* Add an optimized implementation for modern Intel CPUs with AES-NI.
* Add new tests (AES256 key expansion).
* Reimplement the counter mode to work with any block cipher, any endianness
and to take advantage of wide blocks.
* Add benchmarks for AES.
