2021-11-20std: add `writer` methods on all crypto.hash types (#10168)Meghan
2021-08-24remove redundant license headers from zig standard libraryAndrew Kelley
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.

2020-10-17std/crypto: make the whole APIs more consistentFrank Denis
- 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.

2020-08-21Hash functions now accept an option setFrank Denis
- This avoids having multiple `init()` functions for every combination of optional parameters - The API is consistent across all hash functions - New options can be added later without breaking existing applications. For example, this is going to come in handy if we implement parallelization for BLAKE2 and BLAKE3. - We don't have a mix of snake_case and camelCase functions any more, at least in the public crypto API Support for BLAKE2 salt and personalization (more commonly called context) parameters have been implemented by the way to illustrate this.
2020-08-20Remove the reset() function from hash functionsFrank Denis
Justification: - reset() is unnecessary; states that have to be reused can be copied - reset() is error-prone. Copying a previous state prevents forgetting struct members. - reset() forces implementation to store sensitive data (key, initial state) in memory even when they are not needed. - reset() is confusing as it has a different meaning elsewhere in Zig.

2020-08-20Breaking: sort std/crypto functions into categoriesFrank Denis
Instead of having all primitives and constructions share the same namespace, they are now organized by category and function family. Types within the same category are expected to share the exact same API.

2019-11-27remove type coercion from array values to referencesAndrew Kelley
* Implements #3768. This is a sweeping breaking change that requires many (trivial) edits to Zig source code. Array values no longer coerced to slices; however one may use `&` to obtain a reference to an array value, which may then be coerced to a slice. * Adds `IrInstruction::dump`, for debugging purposes. It's useful to call to inspect the instruction when debugging Zig IR. * Fixes bugs with result location semantics. See the new behavior test cases, and compile error test cases. * Fixes bugs with `@typeInfo` not properly resolving const values. * Behavior tests are passing but std lib tests are not yet. There is more work to do before merging this branch.
